The present invention relates to a tray for assembling an electroluminescent device and an electroluminescent device assembling apparatus having the same, and more particularly, to support a sealing cap and a rear glass plate for sealing a light emitting part formed on one surface of a substrate in assembling the electroluminescent device. It relates to a tray and an electroluminescent device assembly having the same.

An electroluminescent device is an active light emitting display device, and has attracted attention as a next generation display device because of its advantages of having a wide viewing angle, excellent contrast, and fast response speed. The electroluminescent device is classified into an inorganic electroluminescent device and an organic electroluminescent device according to whether the material forming the light emitting part is an inorganic material or an organic material. The organic electroluminescent device has excellent characteristics such as brightness and response speed compared to the inorganic electroluminescent device. And it has the advantage that color display is possible.

In the organic light emitting display device illustrated in FIG. 1, a light emitting part 11 is formed on a transparent insulating substrate 10 such as glass, and the light emitting part is laminated on a positive electrode formed in a predetermined pattern on one surface of the substrate. And a negative electrode having a predetermined pattern formed to intersect the positive electrode. The organic layer has a structure in which a hole transport layer, a light emitting layer, and an entire embroidery layer are sequentially stacked, and are made of an organic compound. Materials for forming such an organic layer include phthalocyanine (CuPc: copper phthalocyanine), N, N-di (naphthalen-1-yl) -N, N'-diphenyl-benzidine (N, N'-Di (naphthalene-1- yl) -N, N'-diphenyl-benzidine (NPB), tris-8-hydroxyquinoline aluminum (Alq3), etc. are employ | adopted.

When voltage is applied to the positive electrode and the negative electrode of the organic light emitting device configured as described above, holes injected from the positive electrode are moved to the light emitting layer via the hole transport layer, and electrons are injected from the negative electrode to the light emitting layer via the electron transport layer. do. In this light emitting layer, electrons and holes recombine to produce excitons, and as the excitons change from the excited state to the ground state, the fluorescent molecules in the light emitting layer emit light to form an image.

When the organic light emitting diode is exposed to moisture in the air, it is fatally damaged and cannot be used. Thus, the light emitting part 11 is the metal cap 20 shown in FIG. 1 or the back glass plate 40 shown in FIG. Sealed).

The metal cap 20 includes a peripheral portion 25 in close contact with the substrate and a central portion 24 defining a light emitting portion accommodating portion 22, which is a space for accommodating the light emitting portion. The moisture absorbent isolation member 21 attached to the center portion and the inner portion defines a moisture absorbent accommodating portion 23 in which a moisture absorbent for absorbing moisture or the like that may be present in the light emitting portion accommodating portion is accommodated. The gas can pass through the absorbent isolation member 21 while the absorbent cannot pass through the absorbent isolation member 21. Meanwhile, the peripheral portion 25 of the metal cap is adhered to one surface of the substrate 10 by an adhesive 30.

The back glass plate 40 includes a peripheral portion 45 in close contact with the substrate and a central portion 44 defining a light emitting portion accommodating portion 42, which is a space for accommodating the light emitting portion. The moisture absorbent isolation member 41 attached to the center portion and the inner portion defines a moisture absorbent accommodating portion 43 in which a moisture absorbent for absorbing moisture or the like that may be present in the light emitting portion accommodating portion is accommodated. The gas can pass through the absorbent isolation member 41 while the absorbent cannot pass through the absorbent isolation member 41. Meanwhile, the peripheral portion 45 of the rear glass plate is adhered to one surface of the substrate 10 by an adhesive 30.
