Patent ID: 8599348

Claim:
A horizontal electric field type liquid crystal display device, comprising: a substrate; a gate line and a data line crossing each other with a gate insulating layer therebetween, and defining a pixel area on the substrate; a gate pad formed at one end of the gate line; a data pad formed at one end of the data line; a thin film transistor formed where the gate line and the data line is crossing; a pixel electrode contacting the thin film transistor on the gate insulating layer; a common electrode disposed in parallel with the pixel electrode having a predetermined distance; a passivation layer covering whole surface of the substrate including the pixel electrode and the common electrode; a data pad contact hole exposing some portions of the data pad through the passivation layer; a gate pad contact hole exposing some portions of the gate pad through the passivation layer and the gate insulating layer; a data pad terminal filling in the data pad contact hole and contacting the data pad; and a gate pad terminal filling in the gate pad contact hole and contacting the gate pad, wherein the predetermined distance between the pixel electrode and the common electrode is 0.5˜1.5 times of at least one width of the pixel electrode and the common electrode, such that the horizontal electric field is formed between the pixel electrode and the common electrode and over the pixel electrode and the common electrode.
