Abstract: Pixel electrodes of a display device include plural first pixel electrodes and plural second pixel electrodes which have areas different from each other. Each of plural scanning signal lines is connected with any one of the plural first pixel electrodes and the plural second pixel electrodes through respective transistors. A control circuit applies a first conducting voltage that is a conducting voltage which is applied to the scanning signal lines connected with the first pixel electrodes, and a second conducting voltage that is a conducting voltage which is applied to the scanning signal lines connected with the second pixel electrodes, and different from the first conducting voltage.

Abstract: To obtain a display device that can perform measurements in a wider range and detect characteristic changes with high accuracy while suppressing the increase in circuit size. The display device includes display elements and a characteristic testing unit that tests characteristics of the display elements, and the characteristic testing unit includes a current supply unit for the display element as a target of test, a reference voltage output unit, an output voltage detecting unit that detects a code of a voltage of the test target display element relative to the reference voltage at each time, and a test control unit that allows the reference voltage output unit to sequentially output the reference voltages in response to the codes and acquires a measurement result of the voltage of the test target display element based on the codes.

Abstract: A display device which transmits display data to drive circuits which drive a display panel using low voltage differential signals have input circuits which are hardly influenced by noise. To transmit the low voltage differential signals under the same condition, low voltage differential signal lines are formed in a zigzag pattern so as to make the lengths of the lines equal. To reduce the influence generated by the overlapping of the zigzagged low voltage differential signal lines and the drive circuits, level shift circuits are provided to the input circuits so as to make the input signals assume a stable operation level.
