Claim 0:
1. A display device comprising:
a display panel including a pixel providing a light; and
an input sensing panel configured to sense an external input, the input sensing panel including:
a first sensing insulating layer disposed on the display panel;
a plurality of first conductive patterns disposed on the first sensing insulating layer;
a second sensing insulating layer disposed on the first sensing insulating layer to cover the first conductive patterns;
a plurality of second conductive patterns disposed on the second sensing insulating layer;
a piezoelectric pattern covering the second conductive patterns;
a light blocking pattern covering the piezoelectric pattern and defining a transmission opening configured to transmit light; and
a third sensing insulating layer disposed on the second sensing insulating layer to cover the light blocking pattern,
wherein the piezoelectric pattern is in direct contact with the second conductive patterns, and
a first voltage is applied to the second conductive patterns in a first mode, and a second voltage different from the first voltage is applied to the second conductive patterns in a second mode.
