Problems solved by technology

With the emergence of products such as narrow bezels and full screens, the size of the non-display area of ​​the display panel is limited, so the space for setting alignment marks is limited. The distance between the mark and the wiring in the frame is too close, which will cause the display panel to be damaged by static electricity, which will affect the performance reliability of the display panel

Abstract

The invention discloses a display panel and a display device. The display panel comprises an array substrate, a colored film substrate and an alignment mark structure. A lower alignment mark and an upper alignment mark in the alignment mark structure both comprise at least two marking units, the number of the marking units is the same, the marking units are a 0 marking unit, a 1 markingunit and an N marking unit respectively in the first direction, and after the array substrate is aligned with the colored film substrate, the 0 marking unit in the lower alignment mark is aligned with the 0 marking unit in the upper alignment mark; the width of the projection of the n marking unit in the lower alignment mark on the array substrate in the first direction is samewith that of the projection of the n marking unit in the upper alignment mark on the colored film substrate in the first direction, the distance between two projection centers of two adjacent marking units on the array substrate in the lower alignment mark is X, the distance between two projection centers of two adjacent marking units on the colored film substrate in the upper alignment markis Y, and X is not equal to Y. The device can achieve a suitable alignment function and ensure the reliability of the display panel performance.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] In the existing display device technology, the display panel is mainly divided into two mainstream technologies of a liquid crystal display panel and an organic self-luminous display panel. Among them, the liquid crystal display panel forms an electric field capable of controlling the deflection of the liquid crystal molecules by applying a voltage across the liquid crystal molecules, and then controls the transmission of light to realize the display function of the display panel; the organic self-luminous display panel uses organic electroluminescent materials. When current passes through the organic electroluminescent material, the luminescent material will emit light, thereby realizing the display function of the display panel. [0003] During the manufacturing process of the liquid crystal ...
