Abstract

The invention provides a display panel and a display device. The display panel comprises a first substrate, a second substrate opposite to the first substrate, a liquid crystal layer and a columnar spacer layer, wherein the liquid crystal layer and the columnar isolation pad layer are located between the first substrate and the second substrate. The columnar isolation pad layer comprises at leastone main isolation pad column, the first substrate comprises at least one boss area and a main isolation pad area, the thickness of the first substrate at the main isolation pad area is smaller than that of the first substrate at the boss area, and the main isolation pad column is arranged on the first substrate and located in the main isolation pad area; the thickness of the first substrate at the main isolation pad area is set to be smaller than the thickness of the first substrate at the boss area; and the main isolation pad column is arranged on the first substrate and is positioned in themain isolation pad area, so that the box thickness of the display panel in the boss area is reduced, and the phenomenon of light leakage caused by the fact that the box thickness of the display panelin the boss area is too thick is avoided.

Description

technical field [0001] The present application relates to the display field, in particular to a display panel and a display device. Background technique [0002] LCD (Liquid crystal displays, liquid crystal display) is a widely used flat panel display, which mainly realizes picture display by modulating the light field intensity of the backlight source through liquid crystal switches. [0003] In high-refresh rate and high-resolution display panels such as 120Hz frequency and 8K pixels, with the improvement of display panel resolution and resolution, the further reduction of pixel size will increase the impedance of the circuit in the display panel. Currently, Generally, the resistance is reduced by increasing the thickness of each metal layer in the array substrate, but this structure leads to an increase in the thickness and area of ​​the raised part supporting the PS: (Photo spacer, columnar spacer) in the array substrate, specifically the The protruding part corresponds...
