Display device

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 side of the display panel and configured to reflect the first light toward the first side surface side;
• and
• a drive circuit configured to calculate an output gradation value for each of the pixels based on an input gradation value contained in an image signal, and apply a voltage corresponding to the output gradation value to the pixel, wherein
• the drive circuit is configured to, when the input gradation values corresponding to the pixels are equal to one another, increase and then reduce the output gradation values corresponding to the pixels arranged from the first side surface toward the second side surface along a first direction.

• a second light source device that is located on a lateral side of the display panel and is configured to emit third light to the second side surface side to cause the third light to travel 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 third light quantity of the third 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.
