Abstract: The purpose is providing a vapor deposition mask with high rigidity which can evaporate a uniform thickness film. A vapor deposition mask including a mask body having a main opening, a side surface of the main opening, an upper surface intersecting the side surface, and a lower surface opposing the upper surface, a first insulator contacting the lower surface, and a second insulator contacting the upper and side surfaces, wherein the first insulator includes a first region inside the main opening, and a first opening in the first region, the second insulator includes a second region inside the main opening, and a second opening in the second region, the mask body is sandwiched between the first and second insulators, and one of the first and second insulators includes a region located inside the main opening more centrally than the other and not overlapping with the other and the mask body.

Abstract: An OLED display panel is provided which can control the problem of shedding even in high definition panels. Metal wiring 5 which conducts with an earth line of a flexible printed substrate 15 is provided on a substrate 1. A display area 2 comprised from a plurality of OLED elements is provided at the center of the substrate 1 and four low resistance metal films 3 are provided along each of four edges of the display area 2 on a surface of insulation films 8, 10 at the periphery of the display area 2. Among these, one low resistance metal film 3 conducts with the metal wiring 5 via a contact 3a.
