Abstract

A liquid crystal display ( 2 ) includes: a first substrate ( 20 ); a second substrate ( 22 ); a liquid crystal layer ( 21 ) between the first substrate and the second substrate; and a plurality of pixel regions each defined by respective pixel electrodes ( 224 ) and a common electrode ( 222 ), for application of a voltage to the liquid crystal layer and formation of a fringe electric field at each pixel region. Each pixel region includes a transmissive region (R) and a reflective region (T). A thickness of the liquid crystal layer in the transmissive region is greater than a thickness of the liquid crystal layer in the reflective region.

Claims (15)

1. A liquid crystal display comprising:

a first substrate;

a second substrate;

a liquid crystal layer between the first substrate and the second substrate; and

a plurality of pixel regions each defined by respective pixel electrodes and a common electrode, for application of a voltage to the liquid crystal layer and formation of a fringe electric field at each pixel region;

wherein each of the pixel regions includes a transmissive region and a reflective region, and a thickness of the liquid crystal layer at the transmissive region is greater than a thickness of the liquid crystal layer at the reflective region; and

the common electrode is made of an aluminum film, and has a transmissive area corresponding to the transmissive region and a reflective area corresponding to the reflective region, a thickness of the transmissive area is less than 100 nanometers, and a thickness of the reflective area is more than 100 nanometers.

2. The liquid crystal display of claim 1 , wherein the thickness of the liquid crystal layer in the reflective region is half the thickness of the liquid crystal layer in the transmissive region.

3. A liquid crystal display comprising:

a first substrate;

a second substrate;

a liquid crystal layer between the first substrate and the second substrate;

a plurality of pixel regions each defined by respective pixel electrodes and a common electrode, for application of a voltage to the liquid crystal layer and formation of a fringe electric field at each pixel region, wherein each of the pixel regions includes a transmissive region and a reflective region, and the common electrode has a plurality of transmissive areas corresponding to the transmissive regions of the pixel regions and a plurality of reflective areas corresponding to the reflective regions of the pixel regions; and

a passivation layer positioned corresponding to the reflective regions of the pixel regions, the passivation layer disposed between the first substrate and liquid crystal layer;

wherein the common electrode is made of an aluminum film, and in each of the pixel regions, a thickness of the transmissive area is less than 100 nanometers, and a thickness of the reflective area is more than 100 nanometers.
