Patent ID: 8803153

Claim:
A fringe field switching (FFS) liquid crystal display (LCD) device comprising: a first substrate; a gate line and a data line formed on the first substrate and intersecting each other to define a pixel region; a thin film transistor (TFT) formed in crossing of the gate line and the data line and including a gate electrode, an active layer, and source and drain electrodes; an organic protective film formed on the first substrate with the TFT, the gate line, and the data line formed thereon, and formed of an organic insulating layer; a common electrode formed as a single pattern on the entire first substrate with the organic protective film formed thereon; a low temperature protective film formed on the first substrate with the common electrode formed thereon and including an upper layer and a lower layer, the upper layer having more porous than the lower layer; a pixel electrode formed in the pixel region of the first substrate with the low temperature protective film formed thereon and having a box-like shape with a plurality of slits; and a second substrate attached to the first substrate in a facing manner, wherein a ratio of an Si—H/Si—N bonding of the upper layer of the low temperature protective film is 80% or greater.
