Abstract

The invention discloses a display panel and a display device. The display panel comprises a first underlayer substrate, a liquid crystal layer, a waveguide layer, a grating layer, a quantum dot color filter layer, a first electrode and a second electrode. The first electrode and the second electrode are used for adjusting the refractive index of the liquid crystal layer; the grating layer is used for controlling light to achieve coupling light exiting from the waveguide layer, and the coupling efficiency of coupling light exiting of the waveguide layer is determined according to the difference between the refractive index of the liquid crystal layer and the refractive index of the grating layer. According to the display panel and the display device, it is not needed to arrange a polarizing film in the display panel, the problem of quantum dot depolarization is avoided, and therefore a quantum dot material can be applied to the liquid crystal display device; the transmittance of the display panel is improved; the thickness of a liquid crystal box can be set to be small, and therefore the responding time of liquid crystals is shortened.

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] In the field of display technology, a liquid crystal display device includes a backlight source and a display panel. The display panel includes an array substrate and a color filter substrate oppositely arranged. A liquid crystal layer is arranged between the array substrate and the color filter substrate. Polarizers are arranged on the back side. The deflection of liquid crystal is controlled by voltage and controlled by two layers of polarizers to achieve gray scale display. [0003] In the prior art, the color resistance in the color filter substrate can be made of quantum dot material, and the use of quantum dot material as the color resistance can improve the color gamut of the display panel, but the quantum dot material will destroy the polarization state of the incident light, thus The problem o...
