PROBLEM TO BE SOLVED: To provide an organic electroluminescence device having contact detection function.SOLUTION: A pixel structure of an organic electroluminescence device includes: a scan line SL, a data line DL, bias lines BL1 and BL2, and a readout line RL on a substrate; a first switch element T1; a capacitor C; a driving element T2; an organic light emitting element O; a second switch element T3; and an optical sensor element T4. The first switch element T1 is electrically connected to the scan line SL and the data line DL. The capacitor C is electrically connected to the first switch element T1 and the bias lines BL1 and BL2. The driving element T2 is electrically connected to the first switch element T1, the capacitor C, and the bias lines BL1 and BL2. The organic light emitting element O is electrically connected to the driving element T2. The second switch element T3 is electrically connected to the scan line SL and the readout line RL. The optical sensor element T4 is electrically connected to the second switch element T3 and the bias lines BL1 and BL2. |
