Fringe field switching mode transflective LCD having slits in the reflective area of a pixel electrode that have an inclination angle greater than slits in the transmissive area by about 10 to 40 degrees
First Claim
1. A fringe field switching mode transflective liquid crystal display having a dual cell gap structure, in which a cell gap of a transmissive area is different from a cell gap of a reflective area, the fringe field switching mode transflective liquid crystal display comprising:
- a lower substrate having a counter electrode and a pixel electrode embodied as plurality of slits in respective transmissive and reflective areas;
an upper substrate aligned in opposition to the lower substrate;
a liquid crystal layer interposed between the lower and upper substrates;
an upper polarizing plate aligned at an outer portion of the upper substrate;
a lower polarizing plate aligned at an outer portion of the lower substrate;
a reflective plate provided at an inner portion of the lower substrate in the reflective area by interposing an organic resin layer therebetween;
a lower λ
/2 plate provided between the lower substrate having the reflective plate and the lower polarizing plate; and
an upper λ
/2 plate provided between the upper substrate and the upper polarizing plate, wherein an inclination angle, of slits in the pixel electrode formed in the reflective area are, larger than the inclination angle of slits in the pixel electrode formed in the transmissive area by about 10 to 40°
, a phase delay of the liquid crystal layer formed in the reflective area is in a range of about 0 to λ
/4, and a phase delay of the liquid crystal layer formed in the transmissive area in a range of about 0 to λ
/2.

Abstract
Disclosed is a fringe field switching mode transflective liquid crystal display capable of displaying high quality images. The transflective liquid crystal display includes a lower substrate having a counter electrode and a pixel electrode, an upper substrate aligned in opposition to the lower substrate by interposing a liquid crystal layer therebetween, an upper polarizing plate, a lower polarizing plate, a reflective plate provided at an inner portion of the lower substrate, a lower λ/2 plate, and an upper λ/2 plate. An inclination angle, a slit width and a slit interval of the pixel electrode of the reflective area are different from those of the pixel electrode of the transmissive area. The liquid crystal layer presents a phase delay of about 0 to λ/4 in the reflective area and presents a phase delay of about 0 to λ/2 in the transmissive area.
