Embodiment Construction
[0028] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.
[0029] image 3 Shown is a schematic diagram of partial total reflection occurring in a reflective electrode in a reflective-transmissive liquid crystal display panel. Wherein, 301 is an upper glass substrate, 302 is a reflective electrode, 303 is a transparent electrode, R indicates a reflective area, U indicates a total reflection area, and T indicates a transmissive area. In the R region, the incident light will be reflected by the reflective metal electrode and all exit. In the U region, as shown in the figure, after the incident light is reflected at the reflective electrode, it will be totally reflected at the interface between the glass and the air on the upper substrate, so that this region is a normally black region. The T region is the transmissive region of the reflective-transmissive liquid crystal display panel, and in this region, the backli...

Abstract
The invention relates to a reflection-transmission type liquid crystal display and a manufacturing method thereof. The reflection-transmission type liquid crystal display comprises a plurality of pixels formed by crisscrossing a plurality of data lines and gate lines in arrangement, and each pixel comprises a liquid crystal layer, a reflection electrode, a transparent electrode and a thin film transistor, wherein the liquid crystal layer is arranged between an upper substrate and a lower substrate, the reflection electrode formed in a reflection region realizes reflecting display by employingenvironment light, the transparent electrode formed in a transmission region realizes transmission display by utilizing back light, the thin film transistor comprising a source electrode, a drain electrode and a gate is used to control switch of the pixel, and the source electrode and the drain electrode of the thin film transistor extend to form the reflection electrode and the data line. The reflection-transmission type liquid crystal display can effectively reduce poor display effect caused by reflection of the data lines.
Description
technical field [0001] The invention relates to a reflective transmissive liquid crystal display device and a manufacturing method thereof, in particular to a reflective transmissive liquid crystal display device and a manufacturing method thereof which can effectively reduce light reflection of data lines. Background technique [0002] In recent years, liquid crystal display devices are widely used in information display of electronic products due to their thinness and low power consumption. Liquid crystal display devices are generally classified into reflective liquid crystal display devices, transmissive liquid crystal display devices, and reflective transmissive liquid crystal display devices. [0003] The transmissive liquid crystal display device uses the light of the lighting device arranged behind the liquid crystal display panel to display, and is less affected by the surrounding brightness, and has the advantage of bright and high-contrast display, but has the prob...
