Reflective liquid crystal display panel and display device

Abstract

The invention relates to the technical field of display panels, and discloses a reflective liquid crystal display panel and a display device, and the reflective liquid crystal display panel comprisesan array substrate, a reflective plate, a liquid crystal layer, a transparent electrode layer, a color filter layer, a color film substrate and a polarizing film. The reflecting plate is located between the liquid crystal layer and the array substrate, and the side, away from the array substrate, of the reflecting plate is provided with a grating structure. Optical simulation is carried out through FDTD software, it can be obtained that the reflective liquid crystal display panel can almost completely absorb light with the wavelength of 593 nm under TM polarization, and the color gamut is improved. Meanwhile, the reflectivity of the reflective liquid crystal display panel under TE polarization is very close to the reflectivity of an original aluminum plane reflecting plate, and compared with the mode of adding a light absorbing material in a polarizing film in the prior art, the transmittance loss can be reduced, so that the purpose of improving the display brightness of the reflectiveliquid crystal display panel is achieved.

Description

technical field [0001] The invention relates to the technical field of display panels, in particular to a reflective liquid crystal display panel and a display device. Background technique [0002] With the advancement of technology and the development of society, more and more display panels appear in people's lives, and a reflective liquid crystal display (RLCD, Reflective Liquid Crystal Display) is one of them. [0003] The RLCD in the prior art is equipped with an original aluminum plane reflector to realize light reflection, but the color gamut of this RLCD is small; in order to improve the color gamut, some manufacturers add light-absorbing materials to the polarizer to absorb wavelengths It is 593nm polarized light to improve the color gamut of RLCD. [0004] However, by adding light-absorbing materials to the polarizer to increase the color gamut, the loss of polarized light transmittance is relatively serious; therefore, how to improve the display brightness of RLC...
