| description | Disclosed is a fingerprint recognition sensor including: a backlight unit including a base layer positioned on one surface of a substrate and including a transparent material and a light source irradiating light to the inside of the base layer on one side of the base layer, in which light in which an incident angle on a surface facing the substrate is larger than a critical angle is transmitted toward the substrate; a cover layer spaced apart from the substrate and facing the other surface of the substrate; multiple sensor pixels defined by multiple scan lines and multiple data readout lines on the other surface of the substrate and positioned between the substrate and the cover layer; and multiple photo sensors positioned in the respective sensor pixels and sensing light transmitted on the base layer toward the substrate and total-reflected on a surface contacting a fingerprint of a user on the cover layer. |
