Input sensing device and a display device including the same

An input sensing device, comprising:

• a power line;
• driving lines;
• a first signal line including a first sub-line, a second sub-line, and a third sub-line;
• a second signal line connected to the first signal line;
• and
• sensor pixel groups connected to the power line, the driving lines, and the first signal line,
• wherein at least one sensor pixel group among the sensor pixel groups includes:
• a first optical sensor for transferring a photoelectrically converted charge from the power line to the second sub-line in response to a driving signal provided through a first driving line among the driving lines;
• a second optical sensor for transferring a photoelectrically converted charge from the power line to the second sub-line in response to a driving signal provided through a second driving line among the driving lines;
• and
• a first transistor connected between the first sub-line and the second sub-line, wherein the first transistor includes a gate electrode connected to the first driving line.
