Abstract

The invention provides a display panel which comprises a first liquid crystal panel and a second liquid crystal panel. The first liquid crystal panel and the second liquid crystal panel have VA display modes, the first liquid crystal panel and the second liquid crystal panel are arranged oppositely, and the first liquid crystal panel is arranged on the second liquid crystal panel. The invention further provides a display device provided with the display panel. The display contrast ratio of the display panel formed by stacking the two liquid crystal panels is remarkably increased, and leaked light of the display panel is greatly lowered.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular, relates to a display panel and a display device. Background technique [0002] With the evolution of optoelectronics and semiconductor technology, it has also led to the vigorous development of flat panel displays. Among many flat panel displays, liquid crystal displays (LCD for short) have high space utilization efficiency and low power consumption. , no radiation and low electromagnetic interference and many other superior features have become the mainstream of the market. [0003] A liquid crystal display generally includes a liquid crystal panel and a backlight module, and the backlight module provides display light to the liquid crystal panel, so that the liquid crystal panel displays images. However, in the existing liquid crystal display with a single liquid crystal panel, the display contrast of the single liquid crystal panel is relatively low, and the light leakage ...
