Abstract: A display panel for providing sensing light to an optical fingerprint sensor and a fingerprint sensing system including the display panel are provided. A display panel according to an example embodiment includes a window glass, a phase change layerunder the window glass and delaying a phase of light, a polarizing plate under the phase change layer, a pixel layer under the polarizing plate and having a plurality of pixels each emitting light, and a substrate under the pixel layer and configured to transmit the sensing light generated by scattering light emitted from at least a part of the plurality of pixels by a fingerprint on the window glass.
