Abstract:
1. A liquid crystal display (LCD) device comprising: first and second substrates; a liquid crystal (LC) layer sandwiched between said first substrate and said second substrate, said first substrate defining an array of pixel areas, each of said pixel areas comprising a pixel electrode and a common electrode; and an insulator film formed on said first substrate and on said pixel electrode, the insulator film including a plurality of contact holes and said pixel electrode being exposed through each contact hole of said plurality of contact holes, said each contact hole being positioned above comb-teeth electrodes of said pixel electrode with predetermined intervals such that a voltage supplied to said pixel electrode generates a radial electric field around said each contact hole of said plurality of contact holes and between said pixel electrode and said common electrode so as to control a rotation direction of a LC director at each domain around said each contact hole separately, wherein said radial electric field is generated by and through said each contact hole.
