Abstract:
A liquid crystal display comprising:a first substrate;a plurality of gate lines and a plurality of drain lines formed on the first substrate and defining a plurality of pixels;a thin film transistor for each pixel formed on the first substrate, the thin film transistor having a gate electrode connected to a gate line, a drain electrode connected to a drain line, and source electrode;an inter-layer insulation film having a thickness of at least 3 .mu.m and formed over the thin film transistors, the gate lines and the drain lines;a pixel electrode for each pixel, the pixel electrode being connected to the source electrode of the thin film transistor and at least partially formed on the inter-layer insulation film;a second substrate disposed opposite the first substrate;a liquid crystal layer filled between the first and second substrates; anda common electrode formed on the second substrate, wherein the common electrode defines an orientation control window disposed across the liquid crystal layer from each pixel, the orientation control window being a region on the second substrate free of the common electrode,wherein when a voltage is applied between the common electrode and the pixel electrode, weak electric fields are generated in the vicinity of the orientation control window, and electric fields in a sloped direction are generated around edges of the pixel electrode, so that the horizontal orientation of the liquid crystal molecules in a pixel electrode region is controlled through the weak electric fields and the electric fields in a sloped direction.
