The method includes: forming, between a first substrate and a second substrate, a light-emitting element including an electroluminescence layer and a wiring over which a peeling layer formed by using the material of the electroluminescence layer is provided; and peeling whole of the second substrate from the first substrate so that the peeling layer over the wiring is simultaneously exposed.
Abstract:
An object is to improve productivity related to a laser light irradiation step in a bonding technique of substrates using glass frit. A highly airtight sealing structure or a highly airtight light-emitting device, which can be manufactured with high productivity, is provided. When a glass layer by melting glass frit or a sintered body by sintering glass frit is irradiated with laser light, in order to increase the efficiency, a light-absorbing material is attached to a surface of the glass layer. The laser light irradiation is performed on the light-absorbing material and the glass layer. The substrates are fixed with the glass layer therebetween.

The sealed structure has a first and second substrates, a first surface of the first substrate facing a first surface of the second substrate, and the glass layer which is in contact with the first and second substrates, defines a space between the first and second substrates, and is provided along the periphery of the first surface of the first substrate. The first substrate has a corner portion. The area of the first surface of the first substrate is smaller than or equal to that of the first surface of the second substrate. In at least one of respective welded regions between the glass layer and the first or second substrate, the width of the corner portion is larger than that of the side portion.
Abstract:
A novel display panel that is highly convenient, useful, or reliable is provided. The display panel includes a display region, a first support, and a second support, the display region includes a first region, a second region, and a third region, the first region and the second region each have a belt-like shape extending in one direction, and the third region is sandwiched between the first region and the second region. The first support overlaps with the first region and is less likely to be warped than the third region, and the second support overlaps with the second region and is less likely to be warped than the third region. The second support can pivot on an axis extending in the one direction with respect to the first support.
Abstract:
A touch panel capable of performing display and sensing along a curved surface or a touch panel that maintains high detection sensitivity even when it is curved along a curved surface is provided. A flexible display panel is placed along a curved portion included in a surface of a support. A first film layer is attached along a surface of the display panel by a bonding layer. Second to n-th film layers (n is an integer of 2 or more) are sequentially attached along a surface of the first film layer by bonding layers. A flexible touch sensor is attached along a surface of the n-th film layer by a bonding layer.
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.
Abstract:
A display panel or a display device with high display quality is provided. The display panel includes a light-emitting element, an insulating layer, a protective layer, and a conductive layer. The light-emitting element includes a first electrode, a light-emitting layer, and a second electrode. The light-emitting element emits light to the protective layer side. The insulating layer includes a first opening overlapping with the first electrode. The insulating layer covers an end portion of the first electrode. The light-emitting layer overlaps with the first electrode through the first opening. The second electrode is positioned over the light-emitting layer. The protective layer is over and in contact with the second electrode. The protective layer functions as a protective layer of the light-emitting element. The protective layer includes a second opening overlapping with the insulating layer. The conductive layer is connected to the second electrode through the second opening. The conductive layer functions as an auxiliary wiring of the second electrode.
