Abstract: A display apparatus includes: a substrate; a first display area on the substrate; main subpixels at the first display area; a second display area on the substrate; and a basic unit at the second display area, the basic unit including auxiliary subpixels and a transmission portion. A pixel layout of the auxiliary subpixels is different from a pixel layout of the main subpixels, and a size of a light-emission area of a first auxiliary subpixel from among the auxiliary subpixels is greater than a size of a light-emission area of a first main subpixel from among the main subpixels, the first main subpixel representing the same color as that of the first auxiliary subpixel.
