Abstract

The invention discloses a reflective cholesterol liquid crystal display device which sequentially comprises an upper substrate, an upper alignment layer, a cholesterol liquid crystal layer, a lower alignment layer and a lower substrate from top to bottom, wherein an upper electrode is arranged on the surface of the upper substrate, and a lower electrode is arranged on the surface of the lower substrate. The lower alignment layer is directly adjacent to the cholesterol liquid crystal layer, and the optical density of the lower alignment layer is larger than or equal to 1.

Description

technical field [0001] The present invention relates to a reflective cholesteric liquid crystal display device, in particular to a reflective cholesteric liquid crystal display device whose alignment layer has a specific design. Background technique [0002] Cholesteric liquid crystal (cholesteric liquid crystal) is suitable for use in reflective display devices, such as display devices such as electronic paper, because it can reflect light of different wavelengths by adjusting the pitch of the liquid crystal and has characteristics such as bistable state. However, in a general reflective display device, part of the light may be reflected when passing through the interface between the components of the display device or the film layers, which will reduce the contrast and color saturation of the display device, thereby affecting the display of the display device. quality. Therefore, how to improve the contrast and color saturation of reflective display devices is still one o...
