Embodiment Construction

[0013] The following will clearly and completely describe the technical solutions of each exemplary embodiment provided by the present invention with reference to the accompanying drawings in the embodiments of the present invention. In the case of no conflict, the following embodiments and features in the embodiments can be combined with each other.

[0014] see figure 2 , is the liquid crystal display panel of the first embodiment of the present invention. The liquid crystal display panel 20 includes a relatively spaced array substrate (Thin Film Transistor Substrate, referred to as TFT substrate, also known as a thin film transistor substrate or Array substrate) 21 and a color filter substrate (Color Filter Substrate, referred to as CF substrate, also known as a color filter substrate). sheet substrate) 22 and liquid crystal (liquid crystal molecules) 23 filled between the two substrates. The liquid crystal 23 is located in a liquid crystal cell formed by stacking and se...

Abstract

A liquid crystal display panel (20) and a manufacturing method thereof, and an array substrate (21). A common electrode (224) is disposed at one side of a color filter substrate (22). A pixel electrode (214) is formed in a contact hole of a flat layer (213) of the array substrate (21), and is electrically connected to a drain (D1) of a thin film transistor (212) by means of the contact hole (220). In addition, the pixel electrode (214) has a columnar structure, and a top surface thereof is higher than a top surface of the flat layer (213). The pixel electrodes (214) and the common electrodes (224) are disposed alternately in a direction parallel to the array substrate (21). Based on this method the manufacturing process of the liquid crystal display panel (20) can be simplified, light transmittance thereof can be improved, and the influence of electrical fields on adjacent pixel electrodes (214) can be reduced.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display panel, a manufacturing method thereof, and an array substrate. Background technique [0002] LTPS (Low Temperature Poly-silicon, low-temperature polysilicon technology) liquid crystal display panel has stood out in the display field due to its advantages such as high electron mobility and high brightness. However, its structure has many layers and its manufacturing process is relatively complicated. Such as figure 1 As shown, in the structural design of the existing LTPS liquid crystal display panel 10, the side of the color filter substrate 12 facing the array substrate 11 is provided with a PS (Photo Space, spacer) 121, and the array substrate 11 includes a base material 111 and a Each layer structure on the substrate 111 includes a thin film transistor 112 , a planarization layer (Planarization Layer, PLN) 113 , a pixel electro...
