Abstract

The strength of the whole OLED is increased by proposing a new method of fixing OLED panels. To address the problem, an OLED element is formed on a substrate, and a sealing substrate of a structure by which the substrate is sealed is fixed to a lower metallic frame via an elastic sheet. Silicon resin is preferably used as the sheet, and use of a sheet having a heat diffusion function based on radiation is more desirable.

Claims (10)

1. An organic EL display device,

wherein a lower frame and an upper frame have an engagement structure comprising a snap fit and a notch,

wherein the snap fit comprising a truss structure, which is a hollow triangular sectional shape on a side of the upper frame, and

wherein a side of the lower frame has a notch to insert the snap fit.

2. The organic EL display device of claim 1 ,

wherein a bending part of the upper frame and an edge of the lower frame form a vertex part of another truss structure.

3. The organic EL display device of claim 1 ,

wherein each side of the upper frame has the snap fit and each side of the lower frame has the notch.

4. The organic EL display device of claim 2 ,

wherein each side of the upper frame has the snap fit and each side of the lower frame has the notch.
