    Abstract: A display device includes an active matrix substrate including a plurality of pixels and a driver unit. The driver unit includes a flexible substrate, a first wiring pattern disposed on the flexible substrate, a demultiplexer circuit or a multiplexer circuit supported by the flexible substrate and connected to the first wiring pattern, and a source driver IC supported by the flexible substrate and connected to the first wiring pattern. The driver unit is connected to a display panel, and a TFT of the plurality of pixels and a TFT of the demultiplexer circuit or the multiplexer circuit have semiconductors different from each other.

    Abstract: In a first transition period during which an operation mode transitions from a normal mode to a low power consumption mode, a VCOM generation unit in a power source IC changes a potential of a common electrode drive voltage VCOM from a potential of a first level (for example, 5 V) to a potential of a second level (for example, 12 V) so that a leakage current flowing through a pixel transistor is not generated during a pause period, a gate driver changes a potential of each gate bus line to 0 V, and a source driver changes a potential of each source bus line to 0 V.
