In an embodiment, as shown in FIG. 6, a pixel arranged in the (i?1)th row and the (j?2)th column and a pixel arranged in the (i?1)th row and the (j?1)th column, a pixel arranged in the (i?1)th row the jth column and a pixel arranged in the (i?1)th row and the (j+1)th column, a pixel arranged in the ith row and the (j?2)th column and a pixel arranged in the ith row and the (j?1)th column, a pixel arranged in the ith row and the jth column and a pixel arranged in the ith row and the (j+1)th column, a pixel arranged in the (i+1)th row and the (j?2)th column and a pixel arranged in the (i+1)th row and the (j?1)th column, and a pixel arranged in the (i+1)th row and the jth column and a pixel arranged in the (i+1)th row and the (j+1)th column may respectively share the second contact plugs CP2, for example.
The first contact plugs CP1 and the second contact plugs CP2 may be arranged in the first direction DR1. The first contact plugs CP1 and the second contact plugs CP2 may be alternately arranged with each other in the second direction DR2.
The first voltage line VL1 may include a plurality of first vertical lines (also referred to as first perpendicular lines) VL1v each extending in the first direction DR1. Because the first contact plug CP1 is connected to the first voltage line VL1 to which a first initialization voltage is applied, the first contact plug CP1 may be connected to the first vertical line VL1v.
