Semi-transmitting half-reflection liquid crystal display and manufacturing method thereof

Abstract

Embodiments of the invention provide a transflective liquid crystal display and a method for manufacturing the same. The transflective liquid crystal display comprises: an array substrate; a color filter substrate; a liquid crystal layer interposed between the array substrate and the color filter substrate; a plurality of pixels formed on the array substrate, wherein each pixel comprises a transmissive region and a reflective region, and the liquid crystal layer has the same thickness at the transmissive region and the reflective region; a first transparent electrode formed on the array substrate; a second transparent electrode formed on the color filter substrate at the transmissive region, wherein an initial optical delay of the liquid crystal layer at the transmissive region is different from that of the liquid crystal layer at the reflective region.

Description

technical field [0001] The invention relates to the technical field of liquid crystal displays, in particular to a semi-transmissive and semi-reflective liquid crystal display and a manufacturing method thereof Background technique [0002] A liquid crystal display can be composed of components such as a display screen, a backlight source, and a driving circuit. Specifically, the display screen may include an array substrate, a color filter substrate, and a liquid crystal layer that are boxed together, and the liquid crystal layer fills the gap between the array substrate and the color filter substrate. The principle of displaying images on a liquid crystal display can be based on the fact that when the liquid crystal molecules in the liquid crystal layer rotate with the pressure applied by the drive circuit, the alignment direction of the liquid crystal molecules also changes, resulting in a change in the light that penetrates the liquid crystal molecules. characteristic. ...

Problems solved by technology

[0006] However, the above-mentioned prior art solution is technically difficult to implement, which increases the difficulty of the production process of the transflective liquid crystal display, and also increases the production cost of the transflective liquid crystal display. In semi-reflective liquid crystal displays, the scheme of consistent optical delay in the transmissive area and reflective area of ​​the display screen is very low in feasibility.
