Embodiment Construction

[0040] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0041] see image 3 , the present invention firstly provides a method for manufacturing a CF substrate, comprising the following steps:

[0042] Step 1, such as Figure 4As shown, a base substrate 10 is provided, and a black matrix 20 is formed on the base substrate 10; the black matrix 20 is distributed in a grid on the base substrate 10, so that Several vacant areas 11 arranged in an array are surrounded on the upper side.

[0043] Specifically, the base substrate 10 is a glass substrate.

[0044] Step 2, such as Figure 5 As shown, a common electrode 30 is formed on the base substrate 10 and the black matrix 20 .

[0045] Step 3, if Figure 6-7 As shown, a transparent photoresist layer 40 is formed on the common electrode 30, and the ...

Abstract

The invention provides a CF (Color Filter) substrate, a manufacturing method thereof and a liquid crystal display panel. The manufacturing method of the CF substrate is simple in procedure; the manufactured CF substrate is internally provided with a plurality of planoconcave lenses; the CF substrate is matched with a TFT (Thin Film Transistor) substrate with a color photoresist layer for use; the color photoresist layer comprises a plurality of color resisting units; each planoconcave lens has a diverging effect on light, and can enlarge the angle range of anemergent ray of the corresponding color resisting unit, so that a user can receivetheemergent ray of the color resisting unit when watching a display panel from different angles, and the color cast problem generated when the user watches thedisplay panel aslant is effectively solved. The liquid crystal display panel comprises the CF substrate, and can be used to effectively solve the color cast problem generated when the user watches thedisplay panel aslant.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a CF substrate, a manufacturing method thereof, and a liquid crystal display panel. Background technique [0002] With the development of display technology, liquid crystal displays (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, televisions, personal Various consumer electronic products such as digital assistants, digital cameras, notebook computers, and desktop computers have become the mainstream of display devices. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass substrates. There are many vertical and horizontal small wires between the two glass substrates. The direction of ...
