| description | PROBLEM TO BE SOLVED: To provide a display unit that controls film thickness distribution of a transcriptional light emitting layer within a luminous region and improves the level of display quality. SOLUTION: A transcribed substrate 11 and a donor substrate 40 are so arranged that they face each other with an insulating layer 14 in between, and a laser beam is irradiated to sublimate or evaporize a transfer layer 50 and transcribe it at least to a luminous region 13A. Assuming an intersection of a tangent to the insulating layer 14 drawn from the edge of the luminous region 13A and the surface of the donor substrate 40 is A, and an intersection between a perpendicular drawn from A to the transcribed substrate 11 and the surface of the insulating substrate 14 is C, the light emitting layer 15C is formed so as to include C and preferably not to include D. The film thickness distribution of the light emitting layer 15C within the luminous region 13A and color mixture into the adjacent luminous region 13A are controlled, thus improving the display quality. The distance d in a direction to a line between an edge 13B of the luminous region 13A and the contact surface of the insulating layer 14 and the donor substrate 40 should preferably be 4 μm or more.
