ABSTRACT:
A display unit includes light emitting devices arrayed in such a manner as to be spaced from each other, and a sealing material for covering the surfaces of the light emitting devices, wherein the sealing material has a light diffusion function. The light diffusion function is given to the sealing material by providing a reflection mirror and a half mirror in the sealing material, dispersing, in the sealing material, fine particles having a refractive index different from that of the sealing material, or dispersing bubbles in the sealing material. Since the light diffusion function is given to the sealing material, the light emission region of each of the light emitting devices is substantially enlarged to a size nearly equal to an array pitch of the light emitting devices, to thereby obtain an image display excellent in viewability.
