Abstract: Disclosed are a display device and a driving method thereof. A pixel circuit of the display device may be driven in a data sampling phase and a light emitting phase. A electric current flows in a first effective channel of a driving element in the data sampling phase and a electric current flows in a second effective channel of the driving element in the light-emitting phase.

Abstract: A liquid crystal display device capable of preventing light leakage and vertical crosstalk thereof is disclosed. The liquid crystal display device includes a first substrate in which a pixel region and a data line region next to the pixel region are defined, a data line formed on the data line region of the first substrate with a first insulating film interposed therebetween, two outermost common electrodes of the adjacent two pixels spaced apart from opposite edges of the data line, a shield layer having two segments, each segment has one side of which overlaps an edge of the data line by a width of 0 ?m or more to 2 ?m or less and the other side of which overlaps an edge of one of the two outermost common electrodes with the first insulating film interposed therebetween, and a second substrate bonded opposite to the first substrate.
