Title: Display apparatus

Abstract: According to one embodiment, a display apparatus includes a light modulating unit, a light source unit, a luminance setting unit, a luminance distribution calculating unit, a signal level converting unit, and a control unit. The light source unit includes a basic light source and an extended light source illuminating each of divisional areas into which the display area tentatively divided. The basic light source emits white light with first emission peak wavelengths. The extended light source emits light with a second emission peak wavelength being different from the first emission peak wavelengths and being within a range between shortest and longest wavelengths of the first emission peak wavelengths. The control unit is configured to generate a control signal controlling the basic light source and the extended light source so as to provide a period in which the basic light source and the extended light source simultaneously emit light.
