Patent ID: 7463318

Claim:
A reflective-transmissive type liquid crystal display device, comprising: a first substrate, including: a thin film transistor disposed on a first transparent substrate; an organic insulation layer disposed on the first transparent substrate to insulate the thin film transistor, the organic insulation layer having a contact hole for exposing an output terminal of the thin film transistor; a pixel electrode including a transparent electrode connected to the output terminal of the thin film transistor through the contact hole disposed on the organic insulation layer, and a reflective electrode disposed on the transparent electrode, having an area less than the transparent electrode and defining a first region of the transparent electrode, a portion of the transparent electrode being exposed without being covered by the reflective electrode defining a second region, the second region of the transparent electrode including a first boundary and a second boundary, wherein the first boundary is a boundary between the first and second regions and the second boundary is an exposed edge of the transparent electrode; and an orientation film coated on an upper surface of the pixel electrode and having an orientation groove rubbed in a first direction from the first boundary toward the second boundary, the orientation groove preventing impurity from being stacked at the first boundary of the transparent electrode; a second substrate, including: a color filter disposed on a second transparent substrate in opposition to the pixel electrode; and a common electrode disposed on an upper surface of the color filter and facing the pixel electrode; and a liquid crystal interposed between the first and second substrates.
