ABSTRACT:
A semi-transmission liquid crystal display comprising a liquid crystal panel; a backlight unit to emit light to the liquid crystal panel; and a data driver to apply a data voltage to a data line of the liquid crystal panel; wherein, the liquid crystal panel comprises a TFT substrate which has a transmission area transmitting light from the backlight unit and a reflection area reflecting light from exterior, a color filter substrate which has color filter layer having a concave area which is formed corresponding to the reflection area, and a liquid crystal layer which is sandwiched between the TFT substrate and the color filter substrate and having varying thickness according to the concave area; and the data driver applies the data voltage to the data line in the liquid crystal panel by a transmission voltage mode when the backlight unit is on and by a reflection voltage mode when the backlight unit is off, which configuration provides a semi-transmission LCD having good display quality without an overcoat layer flattening a color filter layer.
