Problems solved by technology

However, for non-COA-designed liquid crystal display panels, there is no color-resist layer as a protective layer between the spacer and the array substrate. At this time, if the spacer is still set corresponding to the TFT device, it may affect the electrical properties of the TFT. Therefore, for non-COA-designed display panels, the spacers can only be set corresponding to the scan lines. In order to ensure that the spacers can still accurately play a supporting role when the array substrate and the color filter substrate are misaligned, it is necessary to increase the scan lines. width, which affects the aperture ratio of the pixel

Embodiment Construction

[0029] 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.

[0030] see image 3 and Figure 4 The present invention provides an array substrate, including a plurality of scanning lines 110 and a plurality of data lines 210, and the plurality of scanning lines 110 and the plurality of data lines 210 are intersected to form a plurality of pixel units 1 arranged in an array. Each pixel unit 1 includes a thin film transistor T and a pixel electrode 300 . The TFT T includes a gate 120 , a source 220 and a drain 230 . The gate 120 of the thin film transistor T of a row of pixel units 1 is correspondingly connected to a scanning line 110, and one of the source 220 and drain 230 of the thin film transistor T of a row of pixel units 1 is correspondingly connected to a data line 210, and each thin film transis...

Abstract

The invention provides an array substrate and a liquid crystal display panel. A grid of a thin film transistor in each pixel unit of the array substrate and a via hole for connecting the thin film transistor to a pixel electrode are respectively located on two sides, close to two adjacent data wires, of the pixel unit, so that a difference of aperture opening ratios of the two sides of the pixel unit is significantly reduced; and a visual angle difference caused by the difference of the aperture opening ratios is effectively solved without affecting the aperture opening ratios, and the displayquality is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an array substrate and a liquid crystal display panel. Background technique [0002] Liquid Crystal Display (LCD) has many advantages such as thin body, power saving, and no radiation, and has been widely used, such as: LCD TV, mobile phone, personal digital assistant (PDA), digital camera, computer screen or Laptop screens, etc., dominate the field of flat panel displays. [0003] Most of the liquid crystal displays 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 pour liquid crystal molecules between the thin film transistor substrate (Thin FilmTransistor Array Substrate, TFT Array Substrate) and the color filter substrate (Color Filter, CF), and apply a driving voltage on the two substrates to Control the rotation direction of th...
