The sealed structure includes a pair of substrates whose respective surfaces face each other with a space therebetween, and a glass layer which is in contact with the substrates, defines a space between the substrates, and has at least one corner portion and side portions in continuity with the corner portion. The width of the corner portion of the glass layer is smaller than or equal to that of the side portion of the same. The sealed structure may comprise a highly reliable light-emitting element including a layer containing a light-emitting organic compound provided between a pair of electrodes.

    Abstract: A display device that can easily have high resolution is provided. A display device having both high display quality and high resolution is provided. A display device with high contrast is provided. A first EL film is deposited in contact with a top surface and a side surface of each of a first pixel electrode and a second pixel electrode each having a tapered shape. A first sacrificial film is formed to cover the first EL film. The first sacrificial film and the first EL film are etched to expose the second pixel electrode and form a first EL layer over the first pixel electrode and a first sacrificial layer over the first EL layer, and then, the first sacrificial layer is removed. The first EL film and the second EL film are etched by dry etching. The first sacrificial layer is removed by wet etching.

    Abstract: When a base film used in a flexible display panel is bonded to a resin member for fixing the base film that is curved, the base film has creases by an environmental change such as temperature due to difference in linear expansion coefficient before and after a thermal shock. A buffer plate that is thin enough to be bent is provided between the base film used in a flexible display panel and the resin member. With the use of heat dissipation effect and heat equalization effect of the buffer plate, a structure around the panel capable of resisting the environmental change can be provided.
