Abstract

The invention provides a color film substrate and a preparation method thereof. The color film substrate is provided with a pixel limiting layer. The pixel limiting layer is provided with a first pixel limiting structure and a second pixel limiting structure, and the second pixel limiting structure wraps the first pixel limiting structure. According to the pixel limiting layer, the structural supporting force of the pixel limiting layer is enhanced while the shading performance and the hydrophobicity of the pixel limiting layer are guaranteed; the pixel limiting layer can reach the target height; and the undercut phenomenon is not likely to happen.

Description

technical field [0001] The invention relates to the display field, in particular to a color filter substrate and a preparation method thereof. Background technique [0002] Organic Light Emitting Diode (OLED) has self-illumination, low driving voltage, high luminous efficiency, short response time, high definition and contrast, nearly 180° viewing angle, wide operating temperature range, flexible display and With many advantages such as large-area full-color display, it is recognized by the industry as an emerging application technology for next-generation flat-panel displays. [0003] At present, due to the excellent properties of high color purity and continuous adjustable spectrum of quantum dot materials (Quantum Dot, QD) itself, it has become the most excellent luminescent material in the 21st century, which can greatly improve the display color gamut of existing liquid crystals. The color performance of the display, so its display application has been extensively stud...
