摘要： A display according to an embodiment of the present invention includes an element substrate, a display section including a plurality of pixels each including a plurality of light-emitting elements, and monitoring elements for detecting the temperature of the light-emitting elements. The light-emitting elements each include an anode, a cathode, and a light-emitting layer placed between the anode and the cathode. The monitoring elements each include an anode, a cathode, and a light emission-suppressing layer containing the same light-emitting material as the light-emitting layer. When voltages are supplied to the monitoring elements, the light emission-suppressing layers do not emit any visible light or emit visible light with a luminance lower than the case where the same voltages as the above voltages are applied to the light-emitting elements.

摘要： An EC region (second region) of an organic EL display device (1) has an optical interference layer which is a multilayer of (i) an edge cover (7) made from an acrylic resin having a lower refractive index, (ii) an organic layer (8), and (iii) a second electrode (9) which is a thin and semi-transparent film. Therefore, the organic EL display device (1) can suppress a deterioration in contrast without narrowing a display region, and can have a high reliability.

摘要： The vapor deposition device includes a plurality of vapor deposition masks whose lengths in Y axis and X axis directions are shorter than those of a film formation target substrate. Vapor deposition masks adjacent to each other in the Y axis direction is positionally displaced in the X axis direction. In an overlapping area in which mask opening group areas adjacent to each other in the Y axis direction overlap with each other in the X axis direction, opening lengths in the Y axis direction become shorter toward the outer side of each of the mask opening group areas in the plan view.
