Semitransparent and semi-reflective liquid crystal display device

Abstract

The invention provides a semitransparent and semi-reflective liquid crystal display device, which comprises a first substrate, a second substrate and a liquid crystal layer, wherein the second substrate is arranged opposite to the first substrate; the liquid crystal layer is formed between the first substrate and the second substrate; a transmission region and a reflecting region are formed between the first substrate and the second substrate; liquid crystal box thicknesses of the transmission region and the reflecting region are equal to each other; a part on the first substrate which corresponds to the reflecting region is provided with a first pixel electrode; the second substrate is provided with a public electrode corresponding to the transmission region and the reflecting region; the second substrate is further provided with a first insulating layer positioned on the public electrode; and a part on the second substrate which corresponds to the transmission region is further provided with a plurality of second pixel electrodes which are positioned on the first insulating layer and are arranged at certain intervals. Due to the adoption of the scheme of the invention, a semitransparent and semi-reflective display effect can be realized; and due to the adoption of an electrode structure in the reflecting region, the display visual angle is expanded, and the contrast is increased; and a single box thickness structure is adopted, so that the difficulty of a process can be lowered.

Description

technical field [0001] The invention relates to the field of liquid crystal display devices, in particular to a transflective liquid crystal display device. Background technique [0002] The liquid crystal display panel is generally formed of a color film substrate and an array substrate in a box, and a liquid crystal layer is encapsulated in the space between the two substrates; since the liquid crystal molecules themselves do not emit light, the display panel needs a light source to display images, depending on the type of light source used , Liquid crystal displays can be divided into transmissive, reflective and transflective. [0003] Among them, the transmissive liquid crystal display panel mainly uses a backlight as a light source, and a backlight is arranged behind the liquid crystal panel, and the pixel electrodes on the array substrate are transparent electrodes as a transmissive area, which is beneficial for the light of the backlight to transmit through the liqui...

AI Technical Summary

Problems solved by technology

[0006] The advantage of the transmissive LCD panel is that it can display bright images in a dark environment, but the disadvantage is that the light that can pass through accounts for a small proportion of the light emitted by the backlight source, and the utilization rate of the backlight source is not high. In order to improve the display brightness, it is necessary to Greatly increase the brightness of the backlight, so the energy consumption is high

[0007] The advantage of the reflective LCD panel is that it can use external light sources, and the power consumption is relatively low, but the disadvantage is that it cannot display images in dark places due to the dependence on external light sources
