Provided are an image display unit capable of enhancing characteristics such as resolution, image quality, and luminous efficiency, facilitating formation of a large-sized screen, and reducing the production cost, and a method of producing the image display unit. The image display unit includes an array of a plurality of light emitting devices for displaying an image in response to a specific image signal, characterized in that an occupied area of each of the light emitting devices is in a range of 25 µ m 2 or more and 10,000 µ m 2 or less, and the light emitting devices are mounted on a wiring board. In mounting the devices, for example, a two-step enlarged transfer is carried out. The two-step enlarged transfer process includes a first transfer step of transferring the devices arrayed on a first substrate onto a temporarily holding member in such a manner that the devices are spaced from each other with a pitch larger than a pitch of the devices arrayed on the first substrate, and holding the devices on the temporarily holding member, and a second transfer step of transferring the devices held on the temporarily holding member onto a second board in such a manner that the devices are spaced from each other with a pitch larger than the pitch of the devices held on the temporarily holding member. Further, a light emitting device is mounted on a wiring board in such a manner that a crystal growth layer of the light emitting device, which is formed by crystal growth, is kept in a posture inverted from a posture thereof at the time of crystal growth in the direction along the normal line of the board principal plane. |
