Display unit, method of manufacturing display unit, and electronic apparatus
View Patent ↗A display unit includes a display panel including a display region and a terminal region on a first substrate, the display region including a plurality of pixels, each of the plurality of pixels including a light emitting element, and the terminal region including a plurality of terminals at a part of a peripheral region of the display region. The light emitting element includes a first electrode, an organic layer, and a second electrode that is provided commonly to the plurality of pixels, in order from the first substrate side. The second electrode extends, continuously in a plan view, to an end of the first substrate in a region on the first substrate except for the terminal region, and is configured to be electrically disconnected from an exterior member of the display panel.
1. A display unit, comprising:
a display panel including a display region and a terminal region, the display region including a plurality of pixels, each of the plurality of pixels including a light emitting element, the terminal region including a plurality of terminals at a part of a peripheral region of the display region, the light emitting element comprising a first electrode, an organic layer, and a second electrode on a first substrate, the second electrode being common to the plurality of pixels,
wherein the second electrode is formed to extend, continuously in a plan view, to cover the display region and the second electrode is also formed to extend across a bezel region between the display region and an edge portion of the display panel at three sides, and the second electrode is formed to be electrically disconnected from an exterior member of the display panel.
2. The display unit according to claim 1 , wherein the second electrode is covered with an insulating film provided at an end of the first substrate.
3. The display unit according to claim 2 , wherein
the display panel has a rectangular shape in a plan view,
the terminal region corresponds to one side of the rectangular shape of the peripheral region on the first substrate, and
the insulating film is provided at ends of the first substrate corresponding to the three sides.
4. The display unit according to claim 1 , wherein
an inverse-tapered structure is provided at a part of the peripheral region in a lower layer of the second electrode, and
the second electrode is electrically discontinuous by the structure while being provided continuously in a plan view.
5. The display unit according to claim 4 , wherein
the structure is provided in the peripheral region on the first substrate to surround the display region.
6. The display unit according to claim 1 , wherein
the display panel includes the first substrate and a second substrate that is provided oppositely to the first substrate and seals the light emitting element, and
the second electrode is disposed inside an outermost end of one or both of the first substrate and the second substrate.
7. The display unit according to claim 6 , wherein
one or both of the first substrate and the second substrate each have a tapered end surface.
8. The display unit according to claim 1 , wherein
the second electrode is a transparent conductive film.
9. The display unit according to claim 1 , further comprising
an organic insulating film as an interlayer insulating film or a pixel separation film, wherein
the organic insulating film has a separation groove in the peripheral region, and
the organic insulating film has an end disposed inside the end of the first substrate.
