A light emitting unit represented by an image display unit includes chips, each of which is formed by burying a light emitting device such as a GaN based semiconductor light emitting device in a resin, wherein external terminals connected to the light emitting device buried in each chip are provided on the chip, and a drive control device such as a pixel transistor for controlling the drive of the light emitting device are connected to the external terminals in a state being at least partially overlapped to the chip. Such an image display unit is advantageous in improving a device density such as a pixel density, enhancing the connection reliability by increasing the diameters of via-holes for wiring without excessively reducing the size of each chip, improving the fabrication yield, facilitating the handling of the chip (or device) at the time of bonding by increasing the apparent area of the chip (or device), and lowering the required specification in terms of alignment accuracy of the chip (or device).
