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.

Display device

A touch sensing unit includes first sensing electrodes (FSEs), second sensing electrodes SSEs, first signal lines (FSLs), second signal lines (SSLs), and connection lines (CLs). The FSEs extend in a first direction (D1) and are arranged in a second direction (D2) intersecting the D1. The SSEs extend in the D2 and are arranged in the D1. The FSLs are connected to the FSEs, respectively. The SSLs are connected to the SSEs, respectively. The CLs are connected to the FSEs via the FSLs. The FSEs are grouped into blocks. Each of the blocks includes p FSEs of the FSEs, and p FSLs connected to the p FSEs, respectively, 'p' being a natural number greater than one. A k-th CL of the CLs is connected to one of the FSEs of each of the blocks, 'k' being a natural number. The FSEs connected to the k-th connection line have different sizes.
