    Abstract: The disclosure relates to a lower display sensor. The lower display sensor includes: a light sensor, including a light irradiation portion that irradiates an induction light used for sensing an object located outside a display, and a light receiving portion that detects a reflected light reflected by the induction light from the object; a first sensor polarizing layer, disposed on an upper portion of the light sensor and having a polarizing axis inclined at a first angle; and a first sensor delay layer, disposed on an upper portion of the sensor polarizing layer and having a slow axis inclined at a first angle with respect to the polarizing axis.

    Abstract: Under-display sensor disclosed. The under-display sensor includes a light selection layer, having a first optical path and a second optical path through which a display circularly-polarized light generated by an ambient light and an unpolarized light generated by a pixel pass, and an optical sensor, having a first receiver configured for measuring light that has passed the first optical path and a second receiver configured for measuring light that has passed the second optical path, wherein the first optical path passes all of the display circularly-polarized light and the unpolarized light, wherein the second optical path blocks the display circularly-polarized light and passes the unpolarized light.
