Description

Technical field: [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display device. Background technique: [0002] With the development of electronic science and technology, liquid crystal displays have been widely used in daily life. However, the display effect of the traditional fully transmissive liquid crystal display cannot meet the requirements of normal use in an environment with strong external light. Therefore, a transflective liquid crystal display device appears. [0003] In the pixel structure of the transflective liquid crystal display, it includes a transmissive part and a reflective part. The transmissive part can emit the backlight from the backlight source to ensure the visibility of the liquid crystal display in a weak light environment; the reflective part includes The reflective metal layer can reflect the incident light from the outside, so as to ensure the contrast of the liquid crystal disp...
