[0025] 1A to 1E are cross-sectional views of a manufacturing method of a color filter substrate according to a first embodiment of the present invention. Please refer to FIG. 1A , the manufacturing method of the color filter substrate of this embodiment includes the following steps. Firstly, a substrate 110 is provided, and a first colored layer 120 is formed on the substrate 110 . Wherein, the material of the first colored layer 120 includes a photoresist material, and the method of forming the first colored layer 120 includes an exposure process and a development process.

[0026] Referring to FIG. 1B , a second colored layer 130 is formed on the substrate 110 , wherein the second colored layer 130 partially overlaps with the first colored layer 120 . In addition, the method of forming the second color layer 130 is the same as the method of forming the first color layer 120 .

[0027] Referring to FIG. 1C , a third colored layer 140 is formed on the substrate 110 , and par...

[0036] FIG. 3 is a cross-sectional view of a color filter substrate according to a second embodiment of the present invention. Please refer to FIG. 3 , this embodiment is similar to the first embodiment, the difference is that: when the light shielding layer 160 is not accurately formed on the common electrode layer 150 above the support S, the light shielding layer 160 above the support S The thickness is inconsistent. Therefore, in the color filter substrate 400 of this embodiment, the light-shielding layer 160 also covers the support S, so the thickness of the light-shielding layer 160 above the support S is relatively easy to control. In addition, when the first color layer 120 is formed, a plurality of alignment marks 170 can also be formed on the substrate 110 at the same time, so as to facilitate the alignment of subsequent masks. In this embodiment, the alignment mark 170 and the first color layer 120 are the same film layer. For example, the alignment mark 170 may b...

Abstract

The invention relates to a method for producing a colorized light-filtering basal plate. The method comprises the following steps: a basal plate is provided; a first color layer, a second color and a third color layer are sequentially formed on the basal plate; and a plurality of supports are formed by partial superposition of any two layers in the first color layer, the second color and the third color layer. A common electrode layer is formed on the basal plate for covering the first color layer, the second color, the third color layer and the supports. A shading layer is formed on the common electrode layer and partially arranged above the supports. Therefore, the method for producing the colorized light-filtering basal plate needs less mask.

Description

technical field [0001] The present invention relates to a semiconductor structure and a manufacturing method thereof, and in particular to a liquid crystal display panel, a color filter substrate and a manufacturing method thereof. Background technique [0002] Due to the increasing demand for displays, the industry is fully committed to the development of related displays. Among them, the cathode ray tube (CRT) has monopolized the display market for many years because of its excellent display quality and technological maturity. However, due to the rise of the concept of green environmental protection, the characteristics of large energy consumption and large radiation, and the limited space for product flattening, it cannot meet the market demand for light, thin, short, small, beautiful and low power consumption. market trends. Therefore, thin film transistor liquid crystal displays (Thin Film Transistor Liquid Crystal Display, TFT-LCD) with superior characteristics such ...
