Abstract

The present aspect relates to a liquid crystal display device including an antistatic structure. In the liquid crystal display device including a first electrostatic discharge (ESD) circuit to prevent static electricity generated from the common voltage pattern and a second ESD circuit to prevent static electricity generated from a data line, the first ESD circuit is floated from a common voltage line and is electrically connected to a common voltage jumping pattern which connects the common voltage line with a common electrode, thereby preventing static electricity generated from the common voltage pattern from flowing into the data line.

Dependent claims

A liquid crystal display device comprising:

a plurality of pixels comprising a pixel electrode, a common electrode and at least one thin film transistor disposed at an intersection of a gate line (GL) and a data line (DL);
at least one common voltage line configured to apply a common voltage to the common electrode;
a common voltage jumping pattern electrically connecting the at least one common voltage line and the common electrode, wherein the common voltage jumping pattern is disposed in a portion of a non-display area;
and
a first electrostatic discharge (ESD) circuit having one end electrically connected to the common voltage jumping pattern.
