A display device includes a substrate having first and second pixel areas that respectively emit first and second light, a first electrode that overlaps the first and second pixel areas, a hole transport region that overlaps the first and second pixel areas, a first organic layer disposed on the first electrode to overlap the first pixel area, a second organic layer disposed on the first electrode to overlap the second pixel area, an electron transport region disposed on the first and second organic layers to overlap the first and second pixel areas, and a second electrode disposed on the first and second organic layers to overlap the first and second pixel areas. The first organic layer includes first emission layers that emit first light and a charge generation layer disposed between the first emission layers. At least one of the first emission layers overlaps the first and second pixel areas.

Display device having common sub-emission layers overlapping different pixel areas

An organic electroluminescence display device includes: a substrate; a first electrode including a first sub-electrode and a second sub-electrode spaced apart from each other and on the substrate; a first light emitting unit on the first electrode; a charge generation unit on the first light emitting unit; a second light emitting unit on the charge generation unit; and a second electrode on the second light emitting unit, wherein the first light emitting unit comprises a first light emitting layer correspondingly on the first sub-electrode; and a second light emitting layer correspondingly on the second sub-electrode, wherein the second light emitting unit comprises a third light emitting layer correspondingly on the first light emitting layer; and a fourth light emitting layer correspondingly on the second light emitting layer.

Organic electroluminescence display device

A liquid crystal display ('LCD') device is capable of consuming relatively less power and significantly reducing flickering that may occur when the LCD device is driven by low frequency, the LCD device including: a liquid crystal layer disposed between the first substrate and the second substrate; a gate line; a data line intersecting the gate line; a timing controller outputting a gate control signal by a frequency of about 15 hertz (Hz) to about 30 Hz; a first electrode on the first substrate; and a second electrode on the first substrate, the second electrode spaced apart from the first electrode. The first electrode includes a plurality of first branch electrodes having an angle of about 9 degrees to about 30 degrees with respect to a normal line which is orthogonal to the gate line.
