Abstract: A display device includes a pixel component including scan lines, data lines, and pixels electrically connected to the scan lines and the data lines, and defining pixel columns and pixel rows, a data driver disposed on a side of the pixel component, and a scan driver disposed on the side of the pixel component. The pixel component includes sub-scan lines, and dummy lines. Each scan line may be electrically connected to the sub-scan lines by contacts. The contacts are divided into contact groups having a same arrangement. The pixel component is divided into pixel blocks corresponding to the contact groups. Each pixel block includes first and second area divided by contact group. The first area is closer to the scan driver than the second area. The pixel component further includes supplementary power lines spaced apart from the respective sub-scan lines.
