Display panel, a display device, and a driving method thereof

Display panel cost and current consumption is reduced by reducing the number of data signal lines than conventional, to provide a display device and a driving method thereof having the same. Each pixel formation portion included in the display unit of the display device (200) (10) includes three sub-pixel formation portion for forming sub-pixels of different color components, respectively (1r, 1 g, 1b) the data signal line extending constructed side by side in the direction. Data signal lines (30), adjacent to the odd-numbered sub-pixel formation portion vertical columns from the scanning signal line extending forwardly (3), the scanning signal line extending direction rearward sub pixel formation portion vertical columns (3) and vice are disposed one by one between the pixel forming section vertical columns (3). Each data signal line (30), the sub-pixel formation portion vertical columns (3,3) is connected, located on both sides thereof. Scanning signal lines (40) are disposed one on each data signal line extending direction sides of the sub-pixel formation portion. Adjacent to each other sub-pixel formation portion vertical columns (3,3) are connected to different scanning signal line (40).
