Abstract
The color filter substrate includes a substrate, a plurality of spaced color filter films disposed on the substrate, a black matrix disposed between adjacent color filter films, and a high refractive transparent layer disposed on a side of the black matrix between the color filter films having different colors away from the substrate, the high refractive transparent layer having a refractive index higher than that of a intermediate medium, and the intermediate medium is a medium filled in a display panel comprising va color filter substrate and a counter substrate. The present disclosure is capable of at least partially solving a problem that the color film substrate cannot simultaneously satisfy the requirements of avoiding cross color and increasing transmittance.
