Abstract

An organic EL panel unit includes: an organic EL panel that displays an image on a front surface of the organic EL panel; and a chassis that is disposed on a rear surface side of the organic EL panel and holds the organic EL panel. The chassis includes a protrusion that protrudes away from the organic EL panel, and the protrusion has a through-hole formed therethrough.

First claim

1 . An organic EL display device, comprising:
an organic EL panel that displays an image on a front surface of the organic EL panel; and a chassis that is disposed on a rear surface side of the organic EL panel and holds the organic EL panel, wherein the chassis includes a protrusion that protrudes away from the organic EL panel, and the protrusion has a through-hole formed therethrough.

2 . The organic EL display device according to claim 1 , wherein
the through-hole is a hole that penetrates through a portion of the protrusion in a protruding direction of the protrusion, and is formed to have, in a plan view, two ends in opposing locations having mutually different widths.

3 . The organic EL display device according to claim 2 , wherein
among the two ends in a plan view of the through-hole, a lower end is greater in width than an upper end.

4 . The organic EL display device according to claim 3 , wherein
among the two ends in a plan view of the through-hole, the lower end is of a size that allows for insertion and removal of a predetermined component, and the upper end is of a size that causes the upper end to engage the predetermined component inserted via the lower end.

5 . The organic EL display device according to claim 2 , wherein
the through-hole includes a first hole and a second hole defined by an outwardly extending portion of an edge of the first hole, the first hole including a wider end among the two ends, and the second hole including a narrower end among the two ends.

6 . The organic EL display device according to claim 2 , wherein
the through-hole is formed to have a region that narrows in width from a first end to a second end among the two ends.

7 . The organic EL display device according to claim 1 , wherein
the protrusion is formed by stamping a portion of the chassis, the chassis being a plate-like component.

8 . The organic EL display device according to claim 1 , wherein
the protrusion includes two through-holes, each of which is the through-hole, formed a predetermined distance apart from each other.

9 . The organic EL display device according to claim 1 , wherein
the protrusion includes a joining section joined to a main body of the chassis, and a protruding section that is connected to the joining section and has the through-hole formed therethrough.

10 . The organic EL display device according to claim 9 , wherein
the chassis includes two protrusions, each of which is the protrusion, joined to the main body of the chassis a predetermined distance apart from each other and, as a result, includes two through-holes, each of which is the through-hole.

11 . The organic EL display device according to claim 8 , wherein
the two through-holes are arranged in the chassis such that a midpoint between the two through-holes is located in a widthwise center of the chassis.

12 . A support stand that supports the organic EL display device according to claim 1 in a standing state, the support stand comprising:
a base;
a column standing on the base; and
a support component extending from the column in a direction intersecting a lengthwise direction of the column,
wherein the support component has an engaging part on a distal end opposite an end at the column, the engaging part engaging with an edge of the through-hole in a state in which the engaging part is inserted in the through-hole.

13 . An image display device, comprising:
the organic EL display device according to claim 1 ; and a back cover disposed on a rear surface side of the organic EL display device.
