A display panel includes a light source section, a light guide section, a liquid crystal layer, a partition section, a display section, and a diffraction section. The light source section emits plural lights of different colors. The light emitted from the light source section enters the light guide section. The light that has passed through the light guide section enters the liquid crystal layer. The partition section partitions the liquid crystal layer into plural pixel regions. The partition section includes plural scanning lines and plural black matrices arranged at intervals in an intersecting direction that intersects with a thickness direction of the light guide section. An image formed by the light emitted from the plural pixel regions is displayed on the display section. The diffraction section diffracts the plural lights that have entered the light guide section from the light source section.

A performance of a display apparatus is improved. A display apparatus includes a glass plate, a display panel facing the glass plate, a frame housing a part of the glass plate and a part of the display panel, and a light source module housed in the frame. The glass plate has a side surface. The display panel includes a first substrate facing the glass plate, a second substrate facing the first substrate, and a liquid crystal layer located between the first substrate and the second substrate. The light source module is disposed at a position facing the side surface of the glass plate.
