    Abstract: According to an aspect, a display device includes a display area portion in which first line segments and second line segments intersect each other and are arranged in a grid to form a non-open portion that divides a light-transmitting opening into open portions, and the open portions form pixels arranged in a matrix. Metal layers are formed on a color filter in the display area portion and disposed in positions overlapping the non-open portion. A metal layer having the largest area in areas overlapping the first line segments among metal layers is the same as a metal layer having the largest area in areas overlapping the second line segments among those of metal layers, and is formed of a metal layer having the highest reflectance among the metal layers.

    Abstract: A display device has a write period of charging a holding capacitor included in each of pixels arranged in a first direction and a second direction different from the first direction in a display region, and has a hold period of holding capacitance of the holding capacitor charged during the write period. The display device comprises a potential maintenance circuit configured to maintain, during the hold period, one of three potential values of a positive-polarity potential, a ground (GND) potential, and a negative-polarity potential having charged the holding capacitor during the write period.
