Abstract

The invention discloses a display panel and a display device, and belongs to the technical field of display. The display panel comprises at least two liquid crystal boxes, wherein the at least two liquid crystal boxes comprise a first liquid crystal box and a second liquid crystal box which are arranged in a stacking manner; the first liquid crystal box comprises a first substrate, a second substrate, and a first polymer network liquid crystal layer arranged between the first substrate and the second substrate in a clamping manner; the second liquid crystal box comprises a third substrate, a fourth substrate, and a second polymer network liquid crystal layer arranged between the third substrate and the fourth substrate; the first liquid crystal box is in a transparent state under an electrical field-free effect and displays a first gray scale under an electrical field effect; the second liquid crystal box is in a transparent state under an electrical field-free effect and displays a second gray scale under the electrical field effect. Compared with the prior art, the display panel disclosed by the invention has the advantages that the display quantity of the gray scales on the display panel can be increased, and the display quality is improved.

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] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a display device provided by the prior art. [0003] figure 1 The display device shown includes a first substrate 01 , a second substrate 02 , and a liquid crystal layer 03 interposed between the first substrate 01 and the second substrate 02 . Wherein, the first substrate 01 includes a first base substrate 011 and a first electrode 012 , and the second substrate 02 includes a second base substrate 021 and a second electrode 022 . [0004] figure 1 In the shown display device, the material of the liquid crystal layer 03 is Polymer Network Liquid Crystals (PNLC for short). In the liquid crystal layer 03, the liquid crystals are distributed in the polymer three-dimensional network to form a continuous channel network...
