Abstract

The invention discloses a liquid crystal display panel and a display device. The liquid crystal display panel comprises a display liquid crystal box, the display liquid crystal box comprises a first opposite substrate, a first array substrate and a first liquid crystal layer, and the first liquid crystal layer is located between the first opposite substrate and the first array substrate; the first liquid crystal layer comprises liquid crystal molecules and dye liquid crystal molecules which are mixed with each other, the display liquid crystal box is provided with a plurality of first pixel units, a first pixel electrode is arranged on the first array substrate, and a first common electrode is arranged on the first opposite substrate; the display liquid crystal box is provided with a quantum dot layer corresponding to the first pixel unit. The liquid crystal molecules and the dye liquid crystal molecules which are mixed with each other are arranged in the display liquid crystal box, and the quantum dot layer is matched to display colors, so that the number of arranged polarizers is reduced, the light transmittance is increased, the contrast ratio is improved, and meanwhile, the display color gamut of a product can be improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display panel and a display device. Background technique [0002] With the development of display technology, the manufacture of display panels is becoming more mature. The display panels provided by the prior art include liquid crystal display panels, organic light-emitting display panels, plasma display panels, and the like. Typical display modes in LCD panels include TN (Twisted Nematic) display mode and IPS (In-Plane Switching) display mode. The contrast ratio of TN display mode and IPS display mode is 1000:1-1200:1, using pixel Optimized design, negative liquid crystal, and optical alignment schemes improve contrast, but it is difficult to meet the requirements of high contrast, and the improvement ratio is limited. It can only increase the contrast ratio to 1500:1-1800:1, and the individual improvement ratio is limited. How to continue to imp...
