However,
Lee 428 discloses in FIG. 11 a display substrate comprising at least part of a plurality of color film patterns (161_R/161_G/161_B; [0154]) partially overlap with a first pattern (mesh of SPL1; [0120]) and the second pattern (mesh of SPL2; [0121]).

And,
C. Nakamura discloses in FIG. 10B light-transmitting portions (30A/30B/30C) of random shapes ([0096]).
Thus, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the structure of Lee and Zhao by using varying widths of Lee and Zhao with the random shapes of Nakamura, such that in the direction perpendicular (normal) to the surface (upper plane) of the base substrate (SUB), the plurality of second light-transmitting openings comprise a first light-transmitting sub-opening at least partially overlapping with the first light-transmitting portion and a second light-transmitting sub-opening at least partially overlapping with the second light-transmitting portion; and in a direction parallel to the surface of the base substrate, a plane shape of the first light-transmitting sub-opening is different from a plane shape of the second light-transmitting sub-opening, for further selectively detecting image data without crosstalk and diffraction between the plurality of light-transmitting portions, improving the accuracy of the image reproduction (Zhao; [0049]-[0053]), and further condensing a sufficient amount of light to correctly display images (Nakamura; [0032]).
Re claim 18, Lee and Zhao and Nakamura disclose the display substrate according to claim 17.
But, do not explicitly disclose wherein a ratio of an area of the first light-transmitting sub-opening (2041 of SP1) to an area of the second light-transmitting sub-opening (2041 of SP2) is greater than or equal to 2.
However, by using the range of widths of Zhao with the random shapes of Nakamura, it would have been obvious through routine experimentation (MPEP § 2144.05) to configure first and second sub-openings wherein a ratio of an area of the first light-transmitting sub-opening to an area of the second light-transmitting sub-opening is greater than or equal to 2 for the image producing structure discussed for claim 17.
Re claim 19, Lee discloses the display substrate according to claim 17, wherein the plurality of sub-pixels (SP) further comprise a third sub-pixel (SP3), a pixel driving circuit (TFT 120 of SP3) of the third sub-pixel (SP3) has a third light-transmitting portion (region of FPSW for SP3), and in the direction perpendicular (normal) to the surface (upper plane) of the base substrate (SUB), the plurality of second light-transmitting openings (Zhao: 2041) further comprise a third light-transmitting sub-opening (2041 of SP3) at least partially overlapping with the third light-transmitting portion (region of FPSW for SP3).
But, fails to disclose in the direction parallel to the surface of the base substrate, a plane shape of the third light-transmitting sub-opening is different from the plane shape of the first light-transmitting sub-opening and the plane shape of the second light-transmitting sub-opening, and an area of the third light-transmitting sub-opening is larger than the area of the second light-transmitting sub-opening, and is substantially equal to the area of the first light-transmitting sub-opening.
However, by using the range of widths of Zhao with the random shapes of Nakamura, it would have been obvious through routine experimentation (MPEP § 2144.05) to configure first, second and third sub-openings wherein a plane shape of the third light-transmitting sub-opening is different from the plane shape of the first light-transmitting sub-opening and the plane shape of the second light-transmitting sub-opening, and an area of the third light-transmitting sub-opening is larger than the area of the second light-transmitting sub-opening, and is substantially equal to the area of the first light-transmitting sub-opening, as part of the image producing structure discussed for claim 17.
