Abstract
A color filter array includes a substrate, a light shielding layer, and color filter patterns. The light shielding layer is on the substrate and has openings exposing a surface of the substrate. Besides, the light shielding layer has a height H. The color filter patterns are located in the openings of the light shielding layer. Each color filter pattern has the maximum film thickness Lc and the minimum film thickness Ls, and the difference between the maximum film thickness Lc and the minimum film thickness Ls is ΔL. The maximum film thickness Lc of each color filter pattern satisfies (m×H)<Lc<(n×H), wherein m comprises about 0.83, n comprises about 0.91, the height H of the light shielding layer satisfies a<H<b, wherein a comprises about 1.6 um and b comprises 2.22 um, and the difference ΔL is less than about 0.39 um.
