The technology relates to a display panel, a display unit, and an electronic apparatus.
In the technical field of display units that perform image display, recently, a display unit employing, as a light-emitting device of a pixel, a current-driven optical device such as an organic electroluminescence (EL) device has been developed, and increasingly commercialized. The current-driven optical device has emission luminance which varies depending on a value of a flowing current. The organic EL device is a self-light-emitting device unlike a device such as a liquid crystal device. The display unit employing the organic EL device (organic EL display unit) therefore does not need a light source (backlight), thus enabling the organic EL display unit to be more lightweight and thinner, and to have higher luminance than a liquid crystal display unit that needs a light source. Further, the organic EL device has a very high response speed of about several micro seconds, thus preventing the occurrence of an afterimage during display of a motion picture. Hence, the organic EL display unit is expected to be a mainstream next-generation flat panel display.
The organic EL display unit is requested to have still higher definition which is also requested likewise for other display units. Under such circumstances, reduction in the number of power lines whose wiring widths are relatively large and sharing a single power line by a plurality of pixel rows are considered. For example, reference is made to Japanese Unexamined Patent Application Publication No. 2011-154287.
