Color filter substrate

A color filter substrate, comprising:

• a transparent substrate, wherein the transparent substrate has a display region and a peripheral region, and the peripheral region surrounds the display region;
• a patterned light-shielding layer disposed on the transparent substrate, wherein the patterned light-shielding layer comprises a first light-shielding pattern disposed on the display region and a second light-shielding pattern disposed on the peripheral region, and the first light-shielding pattern defines a plurality of sub-pixel regions;
• a plurality of color filter units disposed on the display region, wherein each of the color filter units is disposed correspondingly to each of the sub-pixel regions and partially overlaps the first light-shielding pattern;
• and
• a plurality of dummy color filter units disposed on the peripheral region, wherein the second light-shielding pattern is disposed under the dummy color filter units, and spacing between two adjacent dummy color filter units or spacing between the color filter unit and the adjacent dummy color filter unit is wider than spacing between two adjacent color filter units.
