Abstract: Provided in the present disclosure are a display panel and a manufacturing method therefor, and a display apparatus. A pixel defining layer includes a plurality of first barrier walls and a plurality of second barrier walls, which are arranged in an intersecting manner, where a height of the first barrier wall is smaller than a height of the second barrier wall, and orthographic projections of via holes for connecting light emitting devices on a base substrate are located in orthographic projections of the second barrier walls on the base substrate. Due to a great thickness of the second barrier walls, an effect of covering via holes can be better by providing the via holes below the second barrier walls.

Abstract: The present invention relates to a Cu2Zn0.14Sn0.25Te2.34 nanocrystalline solution, its preparation method, a photosensitive resin solution, a method for forming black matrixes (BMs), and a color filter (CF) substrate. As the particle size of nanocrystallines in the nanocrystalline solution is small and light within the ultraviolet-visible light range can be absorbed, the BMs formed by utilization of the nanocrystalline solution can obtain good light shielding performance while having a small thickness. In the nanocrystalline solution, the particle size of the nanocrystallines dispersed in the nanocrystalline solution is 5 to 20 nm; the band gap of the nanocrystallines is 0.8 to 1.5 ev, and the grain surface of the nanocrystallines has organic functional groups.

Abstract translation: 本发明涉及Cu2Zn0.14Sn0.25Te2.34纳米晶体溶液，其制备方法，感光性树脂溶液，形成黑矩阵（BM）的方法和滤色器（CF）基板。 由于纳米晶体溶液中的纳米晶体的粒径小，可以吸收紫外 - 可见光范围内的光，所以利用纳米晶体溶液形成的BM可以获得良好的遮光性能，同时具有较小的厚度。 在纳米晶体溶液中，分散在纳米晶体溶液中的纳米晶体的粒度为5〜20nm; 纳米晶带的带隙为0.8〜1.5ev，纳米晶粒的晶粒表面为有机官能团。
