Abstract

The invention provides a display panel comprising a first substrate, a second substrate, a plurality of pixel structures and at least one cholesterol liquid crystal layer. The first substrate and the second substrate are arranged opposite to each other. The pixel structures are arranged on the first substrate, and each pixel structure comprises a reflection electrode and a light excitation layer. The reflective electrode overlaps the optical excitation layer and is located between the optical excitation layer and the first substrate. The cholesterol liquid crystal layer is arranged between the first substrate and the second substrate.

Description

technical field [0001] The present invention relates to a display technology, in particular to a display panel. Background technique [0002] Generally, thin film transistor liquid crystal display panels (TFT-LCD) can be divided into three categories: transmissive, reflective, and transflective. difference. Among them, the reflective TFT-LCD panel mainly uses the front-light or external light as the light source, and the pixel electrodes on the thin-film transistor array substrate are made of metal or other materials with good reflective properties. The reflective electrode is suitable for reflecting the front light source or external light source. At present, reflective liquid crystal display panels are mostly applied in black and white two-color or black-white-red three-color applications. In order to increase the diversity of colors, it is necessary to set more color filter layers in the light-transmitting area of ​​the pixel, resulting in a decrease in contrast and re...
