摘要： A pixel circuit provided corresponding to a scanning line and a data line includes a transistor and an OLED serving as one example of a light emitting element. In a compensation period, a gate node and a drain node of the transistor are electrically coupled to each other to cause a voltage of the gate node of the transistor to be a voltage corresponding to a threshold voltage. In the gate writing period, a voltage of the gate node of the transistor is varied from a voltage corresponding to the threshold voltage into a voltage corresponding to luminance of the OLED, and the voltage corresponding to luminance of the OLED is applied to the drain node of the transistor.

摘要： The display device includes the first light-emitting element, a second light-emitting element, a first color filter through which light from the first light-emitting element passes, and a second color filter through which the light from the second light-emitting element passes. The relative positional relationship between the center of the first light-emitting element and the center of the first color filter is different from the relative positional relationship between the center of the second light-emitting element and the center of the second color filter.

摘要： Subpixels of R, G, and B corresponding to a scanning line as a first conductive layer extended in a row direction and a data transfer line as a second conductive layer extended in a column direction are provided. A plurality of transistors in the subpixel of each of the colors is disposed along the column direction, and a reflective layer in the subpixel of at least one color is disposed along the row direction so as to overlap any transistor of subpixels of each display color. A center position of a disposition region of a reflective layer in one pixel unit including the subpixels of R, G, and B is different from a center position of a disposition region of a transistor in one pixel unit.
