ABSTRACT:
A display apparatus, includes: a first substrate; a gate line formed over the first substrate; a data line traversing the gate line, and comprising a source electrode; a drain electrode facing the source electrode to define a channel area; a passivation layer formed over the data line and the drain electrode, and comprising an organic material; a pixel electrode formed over the passivation layer, and comprising a first stem electrode, at least a part of which is overlapped with the gate line or the data line, and a plurality of first branch electrodes contacted to the first stem electrode where one set of the first branch electrodes extend longitudinally in a direction different from the longitudinal extension direction of another set of the first branch electrodes so as to thereby cause opposed twisting of corresponding liquid crystal material.
