Display panel and display device

By setting redundant color resists and redundant spacers in the peripheral area of ​​the liquid crystal display panel, and adjusting the height and distribution of the spacers, the image quality problem caused by the difference between the peripheral area and the display area of ​​the liquid crystal display panel was solved, resulting in a more stable display effect and reduced manufacturing costs.

AI Technical Summary

Technical Problem

In existing technologies, the difference in size between the peripheral area and the display area of ​​a liquid crystal display panel causes image quality problems and affects the display effect.

Method used

Redundant color resists and redundant spacers are set in the peripheral area of ​​the liquid crystal display panel. The height and distribution of the spacers are adjusted, and combined with a reasonable proportion of redundant color resists, the difference between the display area and the peripheral area is compensated. The first redundant spacer is filled in the frame adhesive to support the thickness of the liquid crystal cell.

Benefits of technology

It effectively reduces the step difference between the display area and the surrounding area, improves image quality stability, reduces manufacturing costs, and reduces the risk of liquid crystal molecule puncture.

Abstract

The present disclosure provides a display panel and a display device, and belongs to the technical field of display. The display panel of the present disclosure comprises a display area and a peripheral area surrounding the display area; the display panel comprises a first substrate and a second substrate arranged oppositely, a liquid crystal layer, a frame glue, a first redundant spacer filled in the frame glue, and a main spacer and a secondary spacer arranged between the first substrate and the second substrate and located in the display area; the height of the secondary spacer is less than the height of the main spacer; the first substrate comprises a first substrate base plate and a light filtering layer arranged on the side of the first substrate base plate close to the liquid crystal layer; the light filtering layer comprises color resist located in the display area and redundant color resist located in the peripheral area; the first gap is arranged between the first redundant spacers; the orthographic projection of the redundant color resist on the first substrate base plate is located in the orthographic projection of the first gap on the first substrate base plate.
