Problems solved by technology

[0006] In the thin film transistor-liquid crystal display (TFT-LCD) panel manufacturing process, the design and control of the cell thickness is one of the key technologies of the LCD, which directly affects the quality of the display. The thickness of the liquid crystal layer is mainly determined by It is controlled by the photo spacer (PS) between the color filter substrate and the array substrate. Since the height of the spacer is equal on the entire display panel, it is easy to cause changes in the uniformity of the thickness of the liquid crystal cell of the display panel, which affects the quality of the display panel. display effect

Abstract

The invention discloses a display panel and a display device. The display panel comprises a first substrate, a second substrate, a colorful light resistance layer, a liquid crystal layer, a pluralityof interval units, a display area and a peripheral area, wherein the first substrate is provided with a plurality of concave parts; the second substrate comprises a first metal layer; one end of the interval unit in the display area is arranged on the first substrate, and the other end of the interval unit is arranged on the first metal layer; a second metal layer is arranged on the portion, in the peripheral area, of the second substrate; the second metal layer is arranged on the first metal layer, one ends of the interval units of the peripheral area are arranged corresponding to the concaveparts, and the other ends of the interval units of the peripheral area are arranged on the second metal layer; the depth of the concave parts is smaller than twice of the thickness of the second metal layer. A liquid crystal box thickness uniformity of the display panel can be effectively improved, so that the phenomenon that the brightness of the display panel is uneven is effectively alleviated, the display effect of the display panel is better, and the display quality of the display panel is further improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Existing displays are generally controlled based on active switches, which have many advantages such as thin body, power saving, and no radiation, and have been widely used, mainly including liquid crystal displays, OLED (Organic Light-Emitting Diode) displays, QLED (Quantum Dot Light Emitting Diodes) displays, plasma displays, etc. From the perspective of appearance and structure, there are both flat-panel displays and curved-surface displays. [0003] For liquid crystal displays, including two parts of the liquid crystal panel and the backlight module (BacklightModule), the working principle of the liquid crystal display is to place liquid crystal molecules in two parallel glass substrates, and apply a driving voltage on the two glass substrates to control the liquid crystal molecules. The direction o...
