Abstract
The invention, which belongs to the technical field of display, discloses a reflective display panel and a manufacturing method thereof, and a reflective display device. The reflective display panel comprises a first substrate, a second substrate and a liquid crystal grating layer arranged between the first substrate and the second substrate, wherein the first substrate and the second substrate are oppositely arranged. A common electrode layer is arranged on the first substrate; and a pixel electrode layer is arranged on the second substrate. The reflective display panel is provided with sub-pixel units having various colors. The liquid crystal grating layer can reflect light of the corresponding color when the common electrode layer and the pixel electrode layer provide voltages in a first range in any color of sub-pixel unit, so that the reflective display panel is in a bright state. The liquid crystal grating layer can transmit light of all colors when the common electrode layer andthe pixel electrode layer provide voltages in a second range, so that the reflective display panel is in a dark state. According to the reflective display panel, no color film and polaroid are needed; light consumption is reduced; the reflectivity of the reflective display panel is improved; and the thickness of the panel is reduced.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a reflective display panel, a manufacturing method, and a reflective display device. Background technique [0002] Currently, liquid crystal display devices can be classified into three types: transmissive, reflective, and transflective, depending on the type of light source (backlight, external light) used by the display device. Wherein, the reflective display device realizes display by reflecting ambient light incident into the reflective display device. [0003] In the related art, a reflective display device includes a color filter substrate and an array substrate oppositely arranged, a polarizer is arranged on the color filter substrate, and a liquid crystal layer is arranged between the color filter substrate and the array substrate. The liquid crystal monomer in the liquid crystal layer has optical activity, which can rotate the polarization direction of light by 90°. Wh...
