A reflective liquid crystal display panel, its manufacturing method and display device

Abstract

The invention discloses a reflective liquid crystal display panel, a manufacturing method thereof and a display device. When no power is applied, the first alignment layer and the second alignment layer make liquid crystal molecules completely horizontally arranged to form one direction, and the liquid crystal molecules will drive the hands When the liquid crystal molecules turn to one direction, the light of the whole band is not absorbed, but all reflected by the reflective layer, showing a white state; when different voltages are applied to the pixel electrodes, the pixel electrodes and the common electrodes of the liquid crystal molecules in different positions are located. The size of the formed transverse electric field is different, which promotes the different lateral rotation angles of the liquid crystal molecules in different positions, which in turn drives the chiral molecules to rotate at different angles, so that the chiral molecules rotating at different angles can react to the ambient light incident inside the panel. The absorption ratio of the reflective layer is different, and the reflective layer reflects the light of different wavelengths out of the display panel to realize color display. In addition, because the present invention does not need to provide a color resist layer, the transmittance is improved, the brightness and contrast are improved, and the color display effect is better.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a reflective liquid crystal display panel, a manufacturing method thereof and a display device. Background technique [0002] At present, transmissive liquid crystal display (LCD) technology has been widely developed, and many laptop and desktop monitors use transmissive LCDs. The characteristic of transmissive LCD is that it already has quite high resolution and color moving image display capability, and it also has sufficient display brightness. But because the transmissive LCD needs to be equipped with a backlight, the fly in the ointment is that the power consumption is too large, and it occupies a certain space, resulting in thickness and weight that restrict its wider application. For example, it does not meet the requirements of portable applications. [0003] Due to the low power consumption of reflective LCDs, it is expected to be used in portable systems, especially c...

Problems solved by technology

However, in the process of realizing the color display of the color reflective LCD, the external light needs to pass through the three primary color color-resist layers twice, so compared with the transmissive LCD, the image quality is poor, the transmittance is low, the brightness is low, and the contrast is low, resulting in its color image quality. far from meeting the requirements
