Regarding claim 13, Emura teaches the lightguide assembly according to claim 12, further comprising: a first light-emitting member (30left; figure 3B) adjacent to the first connecting portion and facing the first extension region (see figure 3B); a second light-emitting member (30right) adjacent to the second connecting portion and facing the second extension region (see figure 1A; 56a); a third light-emitting member (see figure 3A where plurality of Light emitting members are shown) adjacent to the first connecting portion and facing the connection region (see figure 3A); a fourth light-emitting member (see figure 3A where plurality of Light emitting members are shown) adjacent to the second connecting portion and facing the connection region (see figure 3A). Regarding claim 14, Emura teaches the lightguide assembly according to claim 13, wherein the first light-emitting member (30left; figure 3B) has a first emitting main axis (see figure 3B), the first extension region has a long axis, an angle between the first emitting main axis and the long axis is between 0° and 25° (see figure 3B; paragraph [0079]), the third light-emitting member has a third emitting main axis (see figure 3A), the connection region has a middle section axis, and an angle between the third emitting main axis and the middle section axis is between 15° and 30° (see figure 3B; paragraph [0079]). Regarding claim 15, Emura teaches the lightguide assembly according to claim 13, wherein the connection region comprises a first arc portion (see figure 3B;41), a second arc portion (see figure 3B), and a middle section (see figure 3B; portion where light source 30 is positioned), the first arc portion (41) is connected to the first extension portion at the first connecting portion (see figure 3B), the second arc portion is connected to the second extension portion (56a) at the second connecting portion (see figure 3B), the middle section is connected between the first arc portion and the second arc portion (see figure 3B), a portion of the light-emitting members is adjacent to the first arc portion (see figure 3B;41), and another portion of the light-emitting members (30) is adjacent to the second arc portion (see figure 3B). Regarding claim 16, Emura teaches the lightguide assembly according to claim 12, wherein the light-emitting members comprises: a first light-emitting member (30left; figure 3B) adjacent to the first connecting portion and facing the first extension region (see figure 1A; 55); and a second light-emitting member (30right; figure 3B) adjacent to the second connecting portion and facing the second extension region (see figure 1A; 56a). Regarding claim 17, Emura teaches the lightguide assembly according to claim 16, wherein the first light-emitting member (30left; figure 3B) has a first emitting main axis (see figure 3B), the first extension region (55) has a long axis, and an angle between the first emitting main axis and the long axis is between 0° and 25° (see figure 3B; see paragraph [0079]). Regarding claim 18, Emura teaches the lightguide assembly according to claim 16, wherein the connection region comprises a first arc portion (see figure 3B;41), a second arc portion (see figure 3B), and a middle section (see figure 3B; see where light source 30 is positioned), the first arc portion is connected to the first extension portion at the first connecting portion (see figure 3B), the second arc portion is connected to the second extension portion at the second connecting portion (see figure 3B), the middle section is connected between the first arc portion and the second arc portion (see figure 3B), a portion of the light-emitting members (30) is adjacent to the first arc portion (see figure 3B), and another portion of the light-emitting members (30) is adjacent to the second arc portion (figure 3B). Regarding claim 19, Emura teaches the lightguide assembly according to claim 12, wherein the first extension region has a free end away from the connection region (see figure 3B), and a distribution density of the reflective microstructures (61 and 62) in the first extension region decreases from the connection region to the free end of the first extension region (see figure 1A and 3B). Regarding claim 20, Emura teaches the lightguide assembly according to claim 12, further comprising a light-blocking sheet (33; paragraph [0069]) and a light-reflective sheet (43; paragraph [0069]), wherein the base plate has a first surface and a second surface (see figure 3B), the first surface and the second surface are opposite to each other (see figure 3B), the lightguide member (40) is disposed on the first surface, the light-blocking sheet (33) is disposed on the first surface (see figure 3B), the light-blocking sheet (33) has a gap, lightguide member (40) is arranged to pass through the gap (see figure 3B), and the light-reflective sheet (43) is disposed on the second surface (see figure 3B).
