Patent ID: 7777838

Claim:
A liquid crystal display device, comprising: a first substrate and a second substrate; gate lines and data lines being perpendicular to the gate lines on the first substrate to define a plurality of pixel regions; a thin film transistor at each pixel region, the pixel region including a gate electrode on the first substrate, agate insulating layer on the gate electrode, a semiconductor layer on the gate insulating layer, and a source electrode and a drain electrode on the semiconductor layer; a passivation layer over the first substrate having the thin film transistors; a fluorescent color filter responding to a first light to emit a second light, wherein the fluorescent color filter is on the passivation layer of the first substrate; an intra-cell polarizer on the fluorescent color filter; a black matrix on the passivation layer over the thin film transistors; a pixel electrode over the fluorescent color filter; and a liquid crystal layer between the first and the second substrates,. wherein the whole area of the black matrix on the passivation layer is disposed over a part of the semiconductor layer and the black matrix is directly contacted with the intra-cell polarizer.
