Abstract:
An in plane switching mode liquid crystal display device comprising:a transparent insulating substrate; a gate bus line and a data bus line arranged in a cross fashion on the transparent insulating substrate to define a unit pixel area; a common electrode line disposed in parallel to the gate bus line while being spaced at most apart from the gate bus line in the unit pixel area, the common electrode line having a pair of shields respective disposed at both lateral edges of the unit pixel area; a thin film transistor disposed near an intersection of the gate bus line and the data bus line; a counter electrode arranged in the unit pixel area between the shield of the common electrode line and made of a transparent conductor, the counter electrode including a plurality of branches arranged in parallel to the data bus line, and a bar contacting the common electrode line and connecting respective one-side ends of the branches together; and a pixel electrode formed of a transparent conductor and including a pair of first electrode parts respectively overlapping with the shields of the common electrode line while extending in parallel to the data bus line, second electrode parts interposed each between adjacent ones of the branches included in the counter electrode, and a third electrode part contacting a part of the thin film transistor while connecting together respective one-side ends of the first and second electrode parts.
