Display device and manufacturing method thereof

Abstract

The invention discloses a display device, wherein a wall-shaped electrode is formed on an array substrate, and the wall-shaped electrode separates a row or a column of sub-pixels on a color filter substrate and divides each row or column of sub-pixels into two rows or two columns For the sub-sub-pixels, two rows or two columns of sub-sub-pixels respectively form a light transmission area and a reflection area, and the liquid crystal poured in the light transmission area and the light reflection area makes the light in the transmission area and the reflection area have the same optical path difference. The invention also discloses a manufacturing method of the display device. The present invention can realize the transmissive and reflective display of the display device, without interference from ambient light, strong visibility and energy saving; the thickness of the transmissive area and the reflective area are consistent, the influence of liquid crystal response time is small, and the process is simple; the wall-shaped electrode is adopted, With a high transverse electric field, the driving voltage can be significantly reduced; no compensation film or retarder in the box is required, and the cost is reduced; the transmission area and the reflection area are only different from the liquid crystal, the manufacturing process and circuit driving are simple, and the feasibility is strong.

Description

technical field [0001] The invention belongs to the field of display technology, in particular to a display device and a manufacturing method thereof. Background technique [0002] The transflective liquid crystal display has both the excellent reading performance of the reflective display in outdoor sunlight and the excellent reading performance of the fully transparent display in the dark and weak light environment, so it is widely used in aircraft display instruments, vehicle displays, high-end mobile phones , portable computers and other fields. [0003] The sub-pixels of the transflective liquid crystal display are composed of a transmission area and a reflection area. The transmission area uses a backlight to emit light, and the light only passes through the liquid crystal layer once, while the reflection area relies on reflecting the ambient light source to emit light. The light needs to pass through the liquid crystal layer twice. This makes the optical path differe...

AI Technical Summary

Problems solved by technology

However, different cell thicknesses will result in different liquid crystal response times in the transmissive and reflective regions, which will also increase the difficulty of the manufacturing process and increase the production cost.

In the prior art, there is also a structure of a single-cell thick transflective display device, and its research focuses on the use of different liquid crystal modes in the transmissive area and the reflective area, which makes the manufacturing process and circuit driving more difficult, and the production cost is greatly increased.
