Display device and display unit using the same
A display device is formed by burying at least part of a light emitting device in an insulating material, wherein a drive electrode for the light emitting device is formed so as to be extracted on a surface of the insulating material. A display unit is produced by two-dimensionally arraying such light emitting devices on a base body. Since the display device is modularized by burying a light emitting device finely formed in an insulating material, to re-shape the light emitting device into a size easy to handle, it is possible to suppress the production cost of the display unit using such display devices, and to ensure a desirable handling performance of the light emitting device; for example, facilitate the carrying of the light emitting device or the mounting thereof on a base body.
