DISPLAY PANEL, PREPARATION METHOD THEREFOR, AND DISPLAY APPARATUS

WIPO Patent Application WO/2023/206667

A1

A display panel, a preparation method therefor, and a display apparatus. The display panel comprises a color filter (100). The color filter (100) comprises a substrate layer (10), a black matrix (20), a first color resist layer (30), a second color resist layer (40), and a photo spacer (50). The first color resist layer (30) fills an opening (21) in the black matrix (20) and covers the black matrix (20). The second resist layer (40) is disposed on the first color resist layer (30) and corresponds to the black matrix (20). The photo spacer (50) is provided on the second color resist layer (40), and the projection of the photo spacer (50) on the substrate layer (10) is located within the projection range of the black matrix (20) on the substrate layer (10). By adding the second color resist layer (40), the compression resistance of a display apparatus and the deformation capability and recovery capability of the photo spacer (50) are improved, and the dark-state brightness can be reduced while the shading effect of the color filter (100) is improved, thereby improving the contrast of the display apparatus.
