A vapor deposition mask includes a frame and a metal film supported by the frame, wherein the metal film includes a mask region arranged with a plurality of pixel opening parts corresponding to a display region of a display device, and an alignment region arranged in a periphery of the mask region, the alignment region includes a first opening part and a plurality of second opening parts arranged in a periphery of the first opening part, and a maximum width of the second opening part is smaller than a maximum width of the first opening part.

Vapor deposition mask

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.

Vapor deposition mask and organic EL display device

OLED display panel and manufacturing method thereof

Vapor deposition mask and organic el display device

A display device includes contact holes opened in an insulating film outside of a display area in which pixels are arranged, and having a conductive film exposed in bottom portions, a first metal film formed to cover the contact holes and come in contact with the conductive film of the bottom portions, and a transparent conductive film formed on the first metal film.

Display device with reduced frame size

A display device with a touch panel includes the touch panel having a first substrate having a detection area to detect a coordinate and an outside area in which at least one external terminal is formed, a plurality of first lines to detect the coordinate in the detection area, a plurality of second lines to detect the coordinate in the detection area, wherein each of the plurality of first lines traverse each of the plurality of second lines. An organic emitting display panel is arranged under the touch panel, and a circular polarizing plate arranged at a side of the touch panel opposite to the organic emitting display panel. The organic emitting display panel, the touch panel, and the circular polarizing plate are arranged in this order.

Display device with touch panel

A display device includes a first substrate, an organic EL layer formed on the first substrate and curved in each pixel, and color filters disposed in the respective pixels, and curved to match the organic EL layer. With this configuration, a change in the chromaticity and brightness of the display device depending on a viewing angle of a user is reduced.

A substrate on which a plurality of pixel electrodes are disposed is prepared. An organic electroluminescent filmis formed with the inclusion of a common layer that continuously covers the plural pixel electrodes. A common electrode is formed on the organic electroluminescent film. The common layer is irradiated with an energy ray above areas between the respective adjacent pixel electrodes with the avoidance of irradiation above the plural pixel electrodes. An electric conductivity of the common layer is reduced above the areas between the respective adjacent pixel electrodes, by irradiation of the energy ray. With this configuration, a current leakage can be prevented between the adjacent pixels.
