Problems solved by technology

In the array substrate, the gate insulating layer 4 and the passivation layer 9 are only used to separate the metal layers of different layers in the non-light-transmitting region 1b, but for the pixel electrode 9 and the glass substrate 2 in the light-transmitting region 1a, the gate The insulating layer 4 and the passivation layer 9 are redundant, and part of the light will be lost due to absorption and refraction, thereby reducing the transmittance of light and reducing the utilization rate of the backlight

Abstract

The invention discloses an array substrate. The array substrate comprises a glass substrate and multiple pixel structures formed on the glass substrate, wherein each pixel structure comprises a transmitting area and a non-transmitting area, the non-transmitting area comprises a grid, a grid insulation layer, an active layer, a source / drain and a passivation layer which are sequentially formed on the glass substrate, the transmitting area comprises a pixel electrode directly formed on the glass substrate, and the pixel electrode extends to the non-transmitting area and is electrically connected with the source or the drain. The invention further discloses a preparation method of the array substrate as well as an LCD (liquid crystal display) panel comprising the array substrate.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to an array substrate and a preparation method thereof, and also to a liquid crystal panel including the array substrate. Background technique [0002] Liquid Crystal Display (LCD) is a flat and ultra-thin display device, and the liquid crystal panel is an important part of the liquid crystal display. A commonly used liquid crystal panel at least includes an array substrate and a color filter substrate oppositely arranged, and a liquid crystal layer located between the array substrate and the color filter substrate. [0003] The array substrate generally includes a glass substrate and a plurality of pixel structures formed on the glass substrate. figure 1 It is a structural schematic diagram of an existing array substrate, and only one pixel structure is shown in the figure as an example. Such as figure 1 As shown, the pixel structure 1 includes a light-transmittin...
