Abstract:
1. A liquid crystal display device having a first substrate, a second substrate opposite thereto, a first polarizer with a first transmission axis, a plurality of pixels defined by a plurality of first signal lines and a plurality of second signal lines, and a liquid crystal layer sandwiched between said first substrate and said second substrate, and each of said pixels comprising: a first electrode formed on said first substrate; and a second electrode with at least an opening and at least a stair pattern formed on said second substrate; wherein said stair pattern is formed on a first side of said second electrode in a direction substantially parallel to said first transmission axis, wherein said first side has a length and said stair pattern has a number of first steps corresponding to said length and each said first step has a first sub-side, a second sub-side and a first angle therebetween, wherein said first sub-side has a first length ranged from 1 μm to 20 μm, said second sub-side has a second length ranged from 1 μm to 10 μm, and said first angle is ranged from 90° to 180°.
