Abstract

A display unit includes: a plurality of light emitting elements provided in a display region of a first substrate, and including a first electrode, a light emitting layer, and a second electrode in this order on the first substrate; an auxiliary wiring provided on a second substrate facing the first substrate with the light emitting elements interposed therebetween, and extending from the display region to a peripheral region surrounding the display region; a first pillar configured to electrically connect the auxiliary wiring and the second electrode of the light emitting elements; and a second pillar configured to electrically connect the auxiliary wiring and a peripheral electrode provided in the peripheral region of the first substrate.

Claims (30)

1 . A display unit comprising:

a plurality of light emitting elements provided in a display region of a first substrate, and including a first electrode, a light emitting layer, and a second electrode in this order on the first substrate;

an auxiliary wiring provided on a second substrate facing the first substrate with the light emitting elements interposed therebetween, and extending from the display region to a peripheral region surrounding the display region;

a first pillar configured to electrically connect the auxiliary wiring and the second electrode of the light emitting elements; and

a second pillar configured to electrically connect the auxiliary wiring and a peripheral electrode provided in the peripheral region of the first substrate.

2 . The display unit according to claim 1 , wherein a height of the second pillar is equal to a height of the first pillar.

3 . The display unit according to claim 1 , wherein the second electrode is provided to be common to the plurality of light emitting elements.

4 . The display unit according to claim 3 , further comprising a partition between the light emitting elements next to each other,

wherein the first pillar is provided between the second electrode extending on the partition and the auxiliary wiring.

5 . The display unit according to claim 4 , further comprising an insulating film provided in the peripheral region of the first substrate and having a thickness equal to a thickness of the partition.

6 . The display unit according to claim 5 , wherein

the peripheral electrode includes,

a first contact electrode having a thickness equal to a thickness of the first electrode, and

a second contact electrode provided on the insulating film and having a thickness equal to a thickness of the second electrode, and

the second contact electrode is in contact with the first contact electrode in a connection hole provided in the insulating film.

7 . The display unit according to claim 6 , wherein the first contact electrode is in contact with the second contact electrode in a plurality of connection holes of the insulating film.

8 . The display unit according to claim 1 , wherein the peripheral electrode is electrically connected to a common power supply line.

9 . The display unit according to claim 1 , wherein

the first pillar includes a plurality of first pillars, and the second pillar includes a plurality of second pillars, and

distribution density of the second pillars in the peripheral region is higher than distribution density of the first pillars in the display region.

10 . The display unit according to claim 1 , wherein a thickness of the second pillar is larger than a thickness of the first pillar.

11 . The display unit according to claim 1 , further comprising a filling resin layer provided around the second pillar.

12 . The display unit according to claim 1 , wherein the first pillar and the second pillar have elasticity.

13 . The display unit according to claim 1 , wherein the first pillar and the second pillar each include a formed member containing a resin material, and a conductive film covering the formed member.

14 . The display unit according to claim 1 , wherein the first pillar and the second pillar are configured of a same material.

15 . An electronic apparatus provided with a display unit, the display unit comprising:

a plurality of light emitting elements provided in a display region of a first substrate, and including a first electrode, a light emitting layer, and a second electrode in this order on the first substrate;

an auxiliary wiring provided on a second substrate facing the first substrate with the light emitting elements interposed therebetween, and extending from the display region to a peripheral region surrounding the display region;

a first pillar configured to electrically connect the auxiliary wiring and the second electrode of the light emitting elements; and

a second pillar configured to electrically connect the auxiliary wiring and a peripheral electrode provided in the peripheral region of the first substrate.
