The transflective liquid crystal display comprises an upper base plate and a lower base plate, which respectively include a transmission region and a reflecting region that has unequal liquid crystal box thickness; a glass layer, an ITO transparent electrode, a wideband lambada/4 wave plate and a polarizing disc, which are arranged in sequence from interior to exterior to form the upper base plate and the lower base plate; a passivating layer and a reflecting layer, which are arranged above the internal surface of the lower base plate in the reflection region; a liquid crystal layer that is arranged between the upper base plate and the lower base plate; and orientation layers that are arranged among the liquid crystal layer, the upper base plate and the lower base plate and between the liquid crystal layer and the reflecting layer. The invention configures the liquid crystal box thickness in the transflective region of the liquid crystal display and the anchoring energy of the origination layers so as to obtain excellent transflective region electro-optical characteristics and equal transflective region response time.
Description
One, technical field
The present invention relates to field of liquid crystal display, more particularly, the present invention relates to anti-field of liquid crystal display.
Two, background technology
Transflective lcd mainly is divided into the thick and dual-box thick two big classes of single box.The response time that the thick transflective lcd of single box has anti-district equates, makes advantages such as simple, but owing to there is very big optical path difference between transmission area and the echo area, is difficult to obtain simultaneously very high transmission and reflection efficiency.The dual-box thick transflective lcd just in time characteristic with the thick transflective lcd of single box is opposite, can obtain very high transmission and reflection efficiency simultaneously, but because the thick thick twice of liquid crystal cell that is generally the echo area of liquid crystal cell of transmission area, the response time of transmission area is always greater than response time of echo area like this.The present invention has obtained good saturating anti-district's electro-optical characteristic and the saturating anti-district's response time that equates by reasonably setting transmission area and the thickness of liquid crystal box of echo area and the anchoring energy of oriented layer.
Three, summary of the invention
The present invention proposes the dual-box thick transflective lcd that a kind of anti-district's response time equates, as shown in Figure 1, it is characterized in that each pixel of this transflective lcd is divided into transmission area T and echo area R; The liquid crystal layer 30 of transmission area T and echo area R all uses identical vertical orientated liquid crystal material; The thickness of liquid crystal box of transmission area T and echo area R is respectively d
