Abstract
According to an aspect, a display apparatus includes: a plurality of light sources; a display device that includes a display area provided with npixels and that is irradiated with light from the light sources; a light source controller controlling an operation of the light sources; and a display controller controlling an output gradation value of part or all of the pixels. The display area includes a plurality of partial areas, the partial areas corresponding to the light sources on a one-to-one basis. The light source controller determines the amount of light emitted from each light source corresponding to a corresponding one of the partial areas based on luminance of light required for the corresponding partial area. The display controller performs first correction and second correction when the amounts of light emitted from two light sources corresponding to two adjacent partial areas are different.
