Abstract:
1. A liquid crystal display device, comprising: a gate line on a substrate; a data line defining a pixel region by crossing the gate line; a thin film transistor formed at a crossing position between the gate line and the data line; a passivation layer protecting the thin film transistor; a pixel electrode connected with the thin film transistor; a common electrode generating an electric field with the pixel electrode; and a plurality of grooves on the passivation layer, wherein at least one of the pixel electrode and the common electrode is arranged at intervals in the pixel region, and the grooves are formed at intervals on the passivation layer disposed between the at least one of the pixel electrode and the common electrode arranged at intervals in the pixel region, wherein a difference between a height of the passivation layer with the grooves between the common electrodes or the pixel electrodes and a height of the passivation layer without the grooves is in a range of about 0.1 μm to 0.7 μm.
