Abstract
A color filter substrate and a fabricating method thereof are provided. The color filter substrate has a pixel definition layer having a first pixel-defining structure and a second pixel-defining structure, and the second pixel-defining structure encapsulates the first pixel-defining structure. The pixel definition layer enhances its structural support strength while ensuring its own shading property and hydrophobicity, so that it can reach a target height, and an undercut phenomenon is less likely to occur.
