In this embodiment, the light transmittance of the blue color resist layer 220 and the red color resist layer 210 is relatively low, and an effect similar to a black matrix is caused by a manner of overlapping (color mixing) the blue color resist layer 220 and the red color resist layer 210, so as to achieve a function of shielding light.
It should be noted that the light-shielding region 110 is used to divide and define the setting region of the substrate 100, and has no functionality, that is, the light-shielding region 110 of the substrate 100 itself has no light-shielding effect, and the light-shielding effect of the color filter substrate 100 corresponding to the light-shielding region 110 is realized by stacking the red color resist layer 210, the portion provided in the light-shielding region 110, and the portion provided in the light-shielding region 110 of the blue color resist layer 220.

It is understood that the thickness of the blue color resist layer 220 in the light-shielding region 110 can be adjusted according to the choice of actual conditions and specific requirements, and is not limited herein.

In this embodiment, the width of the portion of the light-shielding region 110 where the red and blue resist layers 210 and 220 are stacked is 50 μm in the first direction X, and the width of the portion of the light-shielding region 110 where the red and blue resist layers 210 and 220 are stacked is 31 μm in the second direction Y.
