Abstract
A technique for obtaining light emitting devices manufactured with high yield is provided. The width of a seal pattern (605b) can be kept thin by manufacturing a light emitting device using a second substrate (600a) which has a concave portion (607a) and a concave portion (608a). It therefore becomes possible to make the light emitting device have a narrow frame. In addition, the light emitting device with the narrow frame can be realized by a manufacturing method thereof in which a portion of the second substrate from the concave portion to an edge surface is cut.
Claims23
A display device comprising:
- a first substrate;
- a second substrate in which at least one concave portion is formed,
- wherein the second substrate and the first substrate are bonded through a sealing material, and
- wherein the sealing material fills the concave portion of the second substrate.
A display device comprising:
- a first substrate;
- and
- a second substrate in which at least one concave portion is formed,
- wherein the second substrate and the first substrate are bonded through a seal pattern, and
- wherein a portion of the seal pattern is formed in a portion of the concave portion.
A display device comprising:
- a first substrate in which a portion of a scribe line is formed;
- and
- a second substrate in which a concave portion is formed,
- wherein the second substrate and the first substrate are bonded through a seal pattern, and
- wherein a portion of the seal pattern is formed in a portion of the concave portion.
A display device comprising:
- a first substrate;
- and
- a second substrate in which a plurality of concave portions are formed,
- wherein the second substrate and the first substrate are bonded through a sealing material, and
- wherein the sealing material fills at least one concave portion of the plurality of concave portions.
A display device comprising:
- a first substrate;
- and
- a second substrate in which a plurality of concave portions are formed,
- wherein the second substrate and the first substrate are bonded through a seal pattern, and
- wherein a portion of the seal pattern is formed in at least one concave portion of the plurality of concave portions.
A display device comprising:
- a first substrate in which a portion of a scribe line is formed;
- and
- a second substrate in which a plurality of concave portions are formed,
- wherein the second substrate and the first substrate are bonded through the seal pattern, and
- wherein a portion of the sealing pattern is formed in at least one concave portion of the plurality of concave portions.
A method of manufacturing a display device, comprising:
- a first step of forming at least one concave portion in a front surface of a second substrate;
- a second step of bonding a first substrate and the second substrate;
- and
- a third step of applying pressure to a rear surface of the second substrate, making cracks develop in the second substrate from the concave portion, and cutting the second substrate.
A method of manufacturing a display device, comprising a step of bonding a first substrate and a second substrate in which at least one concave portion is formed through a seal pattern,
- wherein a step of hardening the seal pattern is performed in a arrangement in which the first substrate is at an upper side and the second substrate is at a lower side.
