An exemplary crystal panel ( 100 ) includes a first substrate ( 110 ), a second substrate ( 120 ) having a common electrode ( 121 ), and a liquid crystal layer ( 130 ) interposed therebetween. The first substrate defines a plurality of pixel regions. Each of the pixel regions includes a thin film transistor ( 140 ), a protection layer ( 170 ), a passivation layer ( 150 ), a pixel electrode ( 160 ). The thin film transistor includes a source ( 142 ), a gate ( 141 ), and a drain ( 143 ). The protection layer is formed at the gate insulating layer at a position corresponding to the drain. The passivation layer is formed at the thin film transistor, and the passivation layer has a contact hole ( 148 ) at position corresponding to the drain. The pixel electrode is formed at the passivation layer and the pixel electrode contacts the drain via the contract hole.
