Patent ID: 8102489

Claim:
A color filter on thin film transistor (COT) type liquid crystal display device, comprising: a pixel region having a plurality of unit pixels defined by intersections of gate and data lines, the gate and data lines formed on a first substrate, wherein the pixel region includes a thin film transistor and sub-color filter layers respectively formed at each of the unit pixels; and a first black matrix formed over the thin film transistor and between the sub-color filters, wherein the first black matrix does not overlap the sub-color filter layers, and wherein the thin film transistor includes a gate electrode, an active layer and source and drain electrodes formed on the first substrate; a passivation layer on the thin film transistor, wherein the first black matrix and the sub-color filters are formed on the passivation layer; a pad region receiving driving signals and applying the driving signals to the gate and data lines; a seal pattern between the pad region and the pixel region; a second black matrix at an outside region, the outside region being between the seal pattern and the pixel region, wherein the second black matrix is formed as an organic film, and is not overlapped with the sub-color filters, and the second black matrix is a portion extended from the first black matrix to a side of the seal pattern; a top case covering the outside region, the top case being overlapped with the second black matrix; an electrostatic discharge circuit between the pad region and the pixel region, the electrostatic discharge circuit formed on the first substrate, wherein the electrostatic discharge circuit does not overlap the second black matrix; a pixel electrode on the sub-color filter layers, wherein the pixel electrode is contact with the drain electrode, and wherein the pixel electrode is not overlapped and is not in contact with the first black matrix and the second black matrix over the thin film transistor and the outside region, respectively; a second substrate facing the first substrate; and a liquid crystal layer between the first and second substrates.
