Problems solved by technology

On the thin film transistor substrate 11, a groove 111 is usually formed on the planar layer (PLN) 110 of the thin film transistor substrate 11 to prevent the PI liquid from crossing the groove and improve the printing accuracy of PI, but this technology The defect is that the thickness of the flat layer 110 is thicker, so that the depth of the groove 111 is deeper, and the slope angle (Taper) formed at the groove 111 is larger, which easily causes the upper film layer to be in the groove. 111 residues, resulting in poor performance of the LCD panel

Embodiment Construction

[0025] The specific implementation manners of the array substrate and the liquid crystal display panel provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] figure 2 It is a schematic diagram of the side structure of the array substrate of the present invention. Please refer to 2. The array substrate 20 of the present invention is divided into a display area A and a frame area B disposed on at least one side of the display area A. In this embodiment, the frame area B surrounds the display area A. In other embodiments of the present invention, the frame area B can also be set only on one side, two sides or three sides of the display area A. . in, figure 2 Only part of the display area A and part of the frame area B are schematically shown.

[0027] The surface of the array substrate 20 has a flat layer 21 extending from the display area A to the frame area B. As shown in FIG. In the frame area B, along ...

Abstract

The invention provides an array substrate and a liquid crystal display. The array substrate has the advantages that a first flow blocking groove and a second flow blocking groove form duplex defense and have the effect of blocking the spreading of materials of alignment film layers, the first flow blocking groove and the second flow blocking groove are shallow grooves, and subsequent depositing film layers cannot be left in the first flow blocking groove and the second flow blocking groove, the subsequent depositing of the film layers cannot be influenced, and the poor performance of the arraysubstrate cannot be caused.

Description

technical field [0001] The invention relates to the field of display devices, in particular to an array substrate and a liquid crystal display panel. Background technique [0002] A liquid crystal display device (LCD, Liquid Crystal Display) has many advantages such as a thin body, power saving, and no radiation, and has been widely used. Wherein, the liquid crystal display device is composed of a liquid crystal display panel and a backlight module arranged on the back of the liquid crystal display panel. The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass substrates, and control the liquid crystal molecules to change direction through whether the glass substrates are energized, and refract light from the backlight module to generate images. [0003] Usually, the liquid crystal display panel is composed of a color filter substrate (CF, ColorFilter), a thin film transistor substrate (TFT, ThinFilmTransisto...
