Problems solved by technology
Generally, the color-resist layer is only set on the display area of the substrate, and the color-resist layer is not set in the non-display area, so ghost points are likely to appear at the edge of the color-resist layer, that is, at the junction of the display area and the non-display area (Ghost mura), resulting in poor display, seriously affecting the picture quality and yield rate of liquid crystal display devices

Abstract
The embodiment of invention discloses a display base board and a production method, an LED panel and an LED device. The display base board comprises a display area, a non-display area surrounding the display area and a substrate. A color barrier layer is arranged in the display area. A flattening layer is located above the color barrier layer, and extends to the non-display layer. The flattening layer which is located in the non-display area comprises a first part and a second part. The distance between first part of the flattening layer and the display area is larger than the distance between the second part of the flattening layer and the display area. The thickness of the first part of the flattening layer is smaller than the thickness of the second part of the flattening layer. An alignment film is located above the flattening layer. Through the technical scheme, the accumulation of the scraps of the alignment film in the intersection between the display area and the non-display area is reduced or avoided, the image quality and passing rate of the LED screen devices are enhanced.
Description
technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display substrate and a manufacturing method, a liquid crystal display panel, and a liquid crystal display device. Background technique [0002] Due to the advantages of thinness and low power consumption, flat panel displays are widely used in portable displays. Among various flat panel displays, liquid crystal display devices have been widely used in computer monitors, notebook computers and televisions due to their advantages of high definition and picture quality. Therefore, improving the image quality and service life of liquid crystal display devices has been favored by numerous scientific researchers and industrial circles. [0003] A conventional liquid crystal display device may be composed of two opposite substrates, on which field generating electrodes such as pixel electrodes and common electrodes are formed. A liquid crystal layer can ...
