Electronic device

An electronic device, comprising:

• a substrate including a first surface and a second surface opposite to the first surface, wherein the first surface includes an active area;
• a first data line and a second data line disposed on the first surface of the substrate and extending along a first direction,
• wherein the active area comprises a first unit region disposed between the first data line and the second data line;
• a first electronic unit disposed on the first surface of the substrate in the first unit region;
• a first control unit disposed on the first surface of the substrate in the first unit region;
• a first scan line crossing the first data line and the second data line, wherein the first control unit is electrically connected between the first electronic unit and the first scan line;
• a first switch element disposed on the first surface of the substrate in the first unit region, and comprising a first gate;
• a first conductive pad disposed on the second surface of the substrate;
• and
• a first signal line electrically connected between the first gate of the first switch element and the first conductive pad.
