Abstract: According to an aspect, a display device includes first to fourth sub-pixels. The first to fourth sub-pixels are each divided into N (N≥2) sub-divided pixels having different areas and can perform N-bit gradation display. Gradation display for a mixed color combining two types out of the first to fourth sub-pixels includes: the N-bit gradation display including 2N-step gradation; and halftone gradation display. In first and second gradation display, an area ratio between the sub-divided pixels driven and those not driven in one of the two types is equal to that in the other of the two types. In the second gradation display, a total area ratio of the sub-divided pixels driven to those not driven is greater than that in the first gradation display. In the halftone gradation display, an area ratio between the sub-divided pixels driven and those not driven is different between the two types.
