Patent ID: 6977706

Claim:
An in-plane switching mode (IPS) liquid crystal display (LCD) comprising: a bottom substrate, at least one pixel area being defined on an upper surface of the bottom substrate; at least one first electrode disposed in the pixel area on the upper surface of the bottom substrate, the first electrode being a protrusion elongated along a first direction; at least one second electrode disposed in the pixel area on the upper surface of the bottom substrate, the second electrode being a protrusion elongated along the first direction, and the second electrode and the first electrode being in an interlaced arrangement; a plurality of bumps formed beneath the first electrode and the second electrode for changing the distribution of the biased electric field to enhance the driving ability of the biased electric field; a conductive layer disposed on a surface of each bump; a top substrate being in parallel with and opposite to the bottom substrate; and a plurality of liquid crystal molecules filled in between the bottom substrate and the top substrate; wherein a longitudinal axis of the liquid crystal molecules is positioned along a second direction and is horizontally arranged between the upper surface of the bottom substrate and a lower surface of the top substrate, and an angle is formed between the second direction and the first direction.
