Abstract
An image display device is a self-luminous type device including a light emitting portion, and a casing portion of a display device unit has a heat dissipating structure portion through which a part of the image display device is exposed for heat dissipation. In manufacturing the display device unit, when performing simple and reliable assembly while securing a high heat dissipation characteristic, for example, by using characteristics of a silicon substrate, high accurate positioning is performed in a display device positioning portion.

11. A video device unit manufacturing method in which a video device unit includes a video device that includes a light emitting portion that generates video light and a casing portion that accommodates the video device, and the casing portion includes a heat dissipating structure portion through which a side of the video device opposite to a side thereof where video light is emitted is exposed for heat dissipation and a video device positioning portion that is in contact with a place other than a place where the video device is exposed and determines an accommodation position of the video device, the method comprising:
-
applying an adhesive for fixing the video device in the video device positioning portion of the casing portion; and positioning the video device and the casing portion and fixing the video device and the casing portion using the adhesive with the video device being exposed through the heat dissipating structure portion.
