Transflective LCD device and method having first domain in reflective portion, second and third domains in transmission portion and with additional electrodes in third domain for third storage electrode
Abstract:
Provided is a transflective LCD device that can selectively use a reflect mode and a transmit mode in a VA mode LCD device having a multiple domain. The transflective LCD device includes: gate lines and data lines arranged to cross each other on a first substrate to define a pixel regions having a reflection portion and a transmission portion; thin film transistors located at each crossing of the gate lines and the data lines, wherein the thin film transistors include a gate electrode, a semiconductor layer, and source/drain electrodes; a transparent electrode connected to the thin film transistor and located in the transmission portion; a reflective electrode connected to the thin film transistor and located in the reflection portion; a connection electrode that electrically connects the transparent electrode with the reflective electrode; a first storage electrode located in the reflection portion and a second storage electrode under the connection electrode; a second substrate facing the first substrate; and a liquid crystal layer interposed between the first and second substrates.
