Embodiment Construction

[0053]The following is a detailed description of preferred embodiments of the present invention with the accompanying drawings. The following descriptions and drawings use the same reference numerals to indicate the same or similar elements, and repeated descriptions of the same or similar elements are omitted.

[0054] figure 1 Shown is a schematic cross-sectional view of a pixel of a transflective liquid crystal display according to an embodiment of the present invention. Each pixel of the transflective liquid crystal display has a transmissive area and a reflective area. In this embodiment, the transmissive area and the reflective area of ​​each pixel adopt the transverse electric field mode Switching mode, IPS) liquid crystal display architecture. In the lateral electric field mode, both the common electrode and the pixel electrode are made on the inner surface of the thin film transistor array substrate, which uses a lateral electric field to drive the liquid crystal mol...

Abstract

A transflective type liquid crystal display comprises a first substrate with a reflective region and a transmission region. A gate region, an insulation layer and a semiconductor layer are sequentially formed on the first substrate. The semiconductor layer has a source region, a drain region and a channel region. A first dielectric layer is disposed on the semiconductor layer and has a through hole to expose a part of the drain region. A first common electrode is disposed on the first dielectric layer and the through hole to cover the exposed part of the drain region. A reflective electrode is disposed on the first dielectric layer located in the reflective region. A second dielectric layer is disposed on the first common electrode and the reflective electrode. A pixel electrode is disposed on the second dielectric layer and connected to the drain region via the through hole.

Description

technical field [0001] The present invention relates to a liquid crystal display, and in particular to a semi-transmissive semi-reflective liquid crystal display with a wide viewing angle Background technique [0002] Generally, the display modes of liquid crystal displays can be roughly divided into transmissive, reflective and transflective. Among them, the transmissive liquid crystal display needs to rely on the backlight source. When the light source penetrates the panel, the panel can produce brightness. Therefore, under the strong sunlight, the screen may not be clearly visible. The reflective (Reflective) technology is to coat the reflective film on the lower glass of the panel, and achieve the purpose of emitting light through an external light source. However, if the ambient light source is weak, the display quality will be poor. [0003] Therefore, a semi-transmissive and semi-reflective liquid crystal display technology has been developed. Due to the characteris...
