The invention provides a semi-transmissive and semi-reflective display device which comprises a first substrate, a second substrate corresponding to the first substrate and a liquid crystal layer arranged between the first substrate and the second substrate, wherein a transmissive area and a reflective area are arranged between the first substrate and the second substrate, and liquid crystal boxes for the transmissive area and the reflective area are of the same thickness; pixel electrodes and common electrodes are respectively arranged on areas on the second substrate corresponding to the transmissive area and the reflective area, and the pixel electrodes and the common electrodes are arranged alternately; a transparent electrode is arranged on an area on the first substrate corresponding to the transmissive area, and the transparent electrode is provided with a covering layer for increasing horizontal electric field components in the liquid crystal box for the transmissive area. The technical scheme of the invention can realize the matching of phase delay of light through the transmissive area and the reflective area to achieve a semi-transmissive and semi-reflective display effect.
Description
technical field [0001] The invention relates to the field of liquid crystal displays, in particular to a transflective liquid crystal display device. Background technique [0002] According to the different types of light sources used, liquid crystal displays can be divided into transmissive, reflective and transflective. Transflective displays combine the advantages of both transmissive and reflective LCDs and can be used both indoors and outdoors. Therefore, it is widely used in display devices for portable mobile electronics. [0003] In order to improve the display quality of liquid crystal displays, achieve higher contrast, faster response time and wider viewing angle, blue phase liquid crystal materials with fast response characteristics have gradually been paid attention to. It is a liquid crystal phase between the cholesteric state and the cholesteric phase, and its temperature range is very narrow, only about 1°C. However, in recent years, it has been found that ...
