Abstract
A color filter substrate includes a transparent substrate, a color photoresist layer and an air guiding layer. The color photoresist layer is disposed on the transparent substrate. The air guiding layer is disposed on the substrate and surrounds the color photoresist layer. The air guiding layer includes a plurality of strip-shaped patterns disposed apart from each other. One end of each of the strip-shaped patterns is connected to the color photoresist layer, and the other end of each of the strip-shaped patterns extends toward a direction far away from the color photoresist layer. An air guiding groove is formed between each two adjacent strip-shaped patterns. A color display apparatus having the color filter substrate is also provided. The color filter substrate can be assembled to the display layer without producing air bubbles, and thereby improves display quality of the color display apparatus.
