Patent ID: 7531838

Claim:
A liquid crystal display comprising: a liquid crystal layer between first and second substrates; a plurality of gate address lines and a plurality of data address lines crossing each other to define a plurality of pixel regions on the first substrate; a thin film transistor and a pixel electrode in each pixel region, the thin film transistor including a semiconductor layer, a gate electrode connected to one of the plurality of gate address lines, a drain electrode connected to one of the plurality of drain address lines, and a source electrode connected to the pixel electrode, the pixel electrode overlapping the gate and data address lines; and an insulating layer between the pixel electrode and the data address lines, a dielectric constant of the insulating layer being no greater than about 3.0 and a thickness of the insulating layer being at least 1.5 μm in the overlapping areas, wherein an aperture ratio of the pixel region is greater than about 65%.
