Abstract: A display apparatus has an enlarged display area so that an image can be displayed in a sensor area. The display apparatus includes: a first base layer that includes a display area that includes a plurality of main pixels and a sensor area that includes a plurality of auxiliary pixels and a transmission portion; a conductive layer positioned on the first base layer and that corresponds to the plurality of auxiliary pixels; and a second base layer positioned on the first base layer with the conductive layer positioned between the second base layer and the first base layer. A resolution of an image displayed by the sensor area is lower than a resolution of an image displayed by the display area.
