Reflective liquid crystal display panel, production method of reflective liquid crystal display panel and display device

Abstract

The invention discloses a reflective liquid crystal display panel, a production method of the reflective liquid crystal display panel and a display device. In an unpowered case, a first alignment layer and a second alignment layer enable liquid crystal molecules to be completely and transversely arranged to form one direction, the liquid crystal molecules can drive chiral molecules to turn to onedirection, and at the moment, light on all wave bands is not absorbed, totally reflected by a reflection layer and displayed in a white state; and when pixel electrodes are applied with different voltages, transverse electric fields formed by the pixel electrodes and common electrodes, in which the liquid crystal molecules at different positions are positioned, are different in size, the liquid crystal molecules at different positions are promoted to have different transverse rotation angles so as to drive the chiral molecules to rotate by different angles, the chiral molecules rotating by different angles are different in absorption ratio for light on different wave bands, which is incident into ambient light inside the panel, and the reflection layer reflects the light on different wavebands out of the display panel to implement color display. Additionally, according to the invention, a color resistance layer does not need to be arranged, and thus, transmissivity is impoved, brightness and a contrast ratio are improved, and a color display effect is excellent.

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
