Abstract: An embodiment of a display device includes: a first display area; a second display area including a transmission area; a third display area between the first display area and the second display area; and a plurality of pixel circuits in the third display area and electrically connected to the plurality of third light-emitting elements, respectively. Each of the plurality of pixel circuits includes: a first thin-film transistor including a first semiconductor layer and a first gate electrode overlapping at least a portion of the first semiconductor layer; a second thin-film transistor including a second semiconductor layer including a material different from that of the first semiconductor layer and a second gate electrode overlapping at least a portion of the second semiconductor layer; and a bottom shielding layer below the second semiconductor layer and overlapping at least a portion of the second semiconductor layer on a plane.

Abstract: A body biasing control circuit capable of being shared by a plurality of macro blocks and can independently control body voltages of a plurality of macro blocks. The body biasing control circuit includes a lookup table for storing a plurality of indexes where each index is associated with a body voltage appropriate for an operating state of a corresponding macro block. A control unit receives a corresponding index from the lookup table and generates a plurality of body voltages appropriate for an operating state of a macro block corresponding to the index and supplies the body voltages to the macro block.
