Abstract

The present invention discloses an encapsulation cap which not only seals simultaneously structural elements formed on two substrates but also has sufficient moisture-absorbing function by using only one getter (moisture absorbent) attached thereto, and a display device using the same. For separating structural elements formed on the glass substrate from the exterior, an encapsulation cap according to the present invention comprises a first surface on which a first recess is formed; and a second surface which is opposite to the first surface and has a second recess formed thereon, wherein the first surface is attached to a first substrate on which structural elements are formed, the second surface is attached to a second substrate on which structural elements are formed, and the structural elements formed on the first and second substrates are received in the first and second recess, respectively.

Claims (9)

1. An encapsulation cap attached onto outer portions of first and second substrates constituting a display device for separating the first and second substrates, the encapsulation cap comprising:

a first surface in which a first recess is formed;

a second surface which is opposite to the first surface and has a second recess formed therein;

at least one penetration hole formed to connect the first recess to the second recess,

wherein the first surface is attached to the first substrate by a first sealant, the second surface is attached to the second substrate by a second sealant.

2. A display device, comprising:

a cap having a first surface on which a first recess is formed, a second surface which is opposite to the first surface and has a second recess formed therein, at least one penetration hole formed to connect the first recess to the second recess; and at least one getter attached on at least one of the first and second recesses to cover the at least one penetration hole;

a first substrate to which the first surface of the cap is attached by a first sealant; and

a second substrate to which the second surface of the cap is attached by a second sealant.
