Patent abstract

A liquid crystal display device comprising: (i) a first substrate and a second substrate positioned apart to define a cell gap, (ii) a liquid crystal layer positioned in the cell gap, and (iii) a plurality of gate lines arranged in a first direction and a plurality of data lines arranged in a second direction substantially perpendicular to the first direction to define a plurality of pixels, each pixel having a first portion and a second portion, and comprising: (a) a first dielectric layer formed on the first substrate, (b) a first pixel electrode formed on the first dielectric layer, (c) a second dielectric layer formed to at least partially cover the first pixel electrode, (d) a second pixel electrode formed on the second dielectric layer such that the second pixel electrode is connectable to the first pixel electrode, and (e) a common electrode formed on the second dielectric layer.
