1. A display device comprising:
a display panel having a display area overlapping a plurality of pixels arranged in a matrix having a row-column configuration in plan view;
a light source device that is located on a lateral side of the display panel and is configured to emit first light to a first side surface side of the display panel to cause the first light to travel toward a second side surface side opposite the first side surface;
a reflective member that is located on the second side surface and configured to reflect the first light as second light from the second side surface side toward the first side surface side; and
a drive circuit configured to calculate an output gradation value for each of the pixels based on a light quantity obtained by summing a first light quantity of the first light and a second light quantity of the second light at the pixel and an input gradation value contained in an image signal, and apply a voltage corresponding to the output gradation value to the pixel.
