As a result, the support base 200 does not interfere with the inspection of the circuit board 51 disposed in the central portion of the chassis 21.
- the through hole 63 and the support member 230 in the modification 3 are linear with each other. You may employ
- the arrangement position of the one or more through holes 60 may be determined so as to be common to a plurality of organic EL panel units 20 having different screen sizes, for example.
- one support base 200 can be commonly used as a tool for supporting the plurality of organic EL panel units 20.
- the number of protrusions 22 in Modification 5 may be 1 or more.
- the two through holes 60 may be arranged in the chassis 21 by joining the two protrusions 22 to the main body of the chassis 21 with a predetermined interval.
- the organic EL panel unit 20 can be stably supported by disposing the protruding portion 22 so that the midpoint of the two through holes 60 is located at the center in the width direction of the chassis 21.
- the present disclosure is useful, for example, for an image display device that is required to be thinned, as an image display device such as a television receiver, a monitor display, a digital signage, a portable terminal, a tablet terminal, or a table-type display device, and
- the image display device can be used as an organic EL display device.
