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.
