Abstract

The invention provides a reflective liquid crystal display panel. The reflective liquid crystal display panel comprises a first substrate, a second substrate and a liquid crystal layer located betweenthe first substrate and the second substrate, the reflective liquid crystal display panel is provided with a plurality of pixel units arranged in an array mode, and each pixel unit comprises a pre-tilt area and a flat area arranged around the pre-tilt area; a common electrode, a plurality of reflective pixel electrodes and an insulating layer covering the pixel electrodes are arranged on the side, facing the liquid crystal layer, of the first substrate, and each pixel electrode is located in the corresponding pixel unit. And the thickness of the insulating layer is gradually reduced from theedge of the pre-inclined region to the center of the pre-inclined region. According to the reflective liquid crystal display panel, dark-state light leakage can be avoided, the contrast ratio can be improved, the conical groove formed by the insulating layer plays a role in assisting deflection of liquid crystal molecules, and the response speed is increased.

Description

technical field [0001] The invention relates to the field of display technology, and more particularly to a reflective liquid crystal display panel. Background technique [0002] With the rapid development of display technology, various technologies emerge in an endless stream, and the applied products are also various. The previous form of relying on drawing paper to display publicity has been gradually replaced by display screens, which are not only diversified, but also energy-saving and environmentally friendly. For example, electronic labels used to replace traditional paper labels are favored by shopping malls, and shopping malls no longer need to worry about frequently posting price tags. [0003] Electronic tags often use reflective liquid crystal display panels, relying on reflected natural light to achieve display. figure 1 It is a structural schematic diagram of a reflective liquid crystal display panel in the prior art, please refer to figure 1 A reflective li...
