Abstract
The present invention provides a manufacturing method of a liquid crystal display panel, the color filter layer is formed on the TFT array substrate, at least a portion of the first color resist layer disposed on the gate line of the first substrate is used as a color resist protrusion, the spacer material and the black matrix material are integrated into same material, and the spacer and the black matrix are formed on the TFT array substrate through utilizing a multi-tone mask and only one lithography process.
Claims18
A manufacturing method of a liquid crystal display panel, comprising:
- a step S40 of using a first mask to process a color filter film, such that the color filter film is formed with a pixel unit region and a light barrier region separated from each other, wherein at least a part of a first color resist layer is disposed on a gate line of a first substrate;
- a step S50 of depositing a first passivation layer on the first color resist layer to form a via of the passivation layer, and then forming a pattern of a plurality of pixel electrodes;
- a step S60 of coating a first photoresist layer on the first passivation layer;
- a step S70 of patterning the first photoresist layer by a multi-tone mask to form a first protrusion, a second protrusion, and a black matrix, wherein the first protrusion is located above the first color resist disposed on the gate line, color of color resist units of the first protrusion and color of color resist units of the second protrusion adjacent to each other is same;
- and
- a step S80 of aligning and attaching a second substrate to the first substrate, and instilling a liquid crystal material into a space between the second substrate and the first substrate.
