Abstract
A display substrate including a base substrate and an optical functional layer provided on the base substrate. The optical functional layer includes a black matrix providing a plurality of first shading strips and a plurality of second shading strips. The plurality of first shading strips intersect with the plurality of second shading strips so as to divide the display substrate into a plurality of pixel units. A thickness of the first shading strips is different from that of the second shading strips.
Claims13
A display substrate, comprising:
- a base substrate and an optical functional layer provided on the base substrate, wherein the optical functional layer comprises a black matrix and a plurality of color filtering blocks, the black matrix comprises a plurality of first shading strips and a plurality of second shading strips, the plurality of first shading strips intersect with the plurality of second shading strips so as to divide the display substrate into a plurality of pixel units, each of the pixel units is provided therein with one of the plurality of color filtering blocks, and a thickness of the first shading strips is larger than that of the second shading strips,
- wherein each of the first and second shading strips is configured to shield light and avoid light leakage, and the black matrix is made of a positive photoresist material or a negative photoresist material.
