Abstract: A shift register includes stages each constituted by a unit circuit provided with a thin-film transistor (separation transistor) that separates a control node into an output-side first control node and an input-side second control node and a capacitor whose first end is connected to the second control node. The thin-film transistor (separation transistor) has a control terminal that is supplied with a high-level DC power supply voltage. Typically, the channel width of a thin-film transistor (first output control transistor) that controls output from a unit circuit is ten or more times greater than the channel width of the thin-film transistor (separation transistor).

Abstract: A set circuit in a unit circuit in a gate driver of a display device includes a setting transistor, a first auxiliary transistor, and a second auxiliary transistor. The setting transistor includes a source terminal connected to an internal node, a gate terminal connected to a set input terminal, and a drain terminal connected to the set input terminal via the first auxiliary transistor and also connected to an input terminal via the second auxiliary transistor in a diode-connected form. Each transistor is controlled to be in an on state and an off state during normal drive and is controlled to be in the off state and the on state during a pause period by a control signal supplied to the input terminal.

Abstract: An image pickup device capable of suppressing breakage of a support leg mounting member is obtained. This image pickup device comprises a housing constituting the body of the image pickup device, a support leg mounting member, rotatably provided on the housing, having a second screw portion fitted with a first screw portion of a support leg supporting the body of the image pickup device and an engaging portion and a plate spring member having a protrusion engaging with the engaging portion of the support leg mounting member. The engaging portion of the support leg mounting member presses the protrusion of the plate spring member for disengaging the support leg mounting member and the protrusion of the plate spring member from each other if force exceeding first force is applied to the support leg mounting member in a first rotational direction when the first screw portion of the support leg is clamped to the second screw portion of the support leg mounting member in the first rotational direction.
