Abstract
A color filter substrate including a substrate, a light shading structure, and a plurality of color filter units is provided. The substrate has a display region and a non-display region. The light shading structure disposed on the substrate includes a black matrix layer and a light shading layer, wherein the black matrix layer is disposed on the substrate and defines a plurality of sub-pixel regions in the display region, and covers the non-display region adjacent to the edge of the display region; the light shading layer is disposed on the black matrix layer of the non-display region adjacent to the edge of the display region and has at least one channel. The color filter units are correspondingly disposed in the sub-pixel regions.
