panel 100 includes a first substrate not shown and a second substrate not shown the first substrate is sealed with the second substrate by a sealant not shown in addition a pixel not shown constituted by a transistor a capacitor an organic light emitting diode etc is formed on the first substrate the thicknesses of the first substrate and the second substrate are set to be different from each other in order to reinforce the strength of the panel 100 the frame 110 protects the sides and the rear surface of the panel 100 the strength of the organic light emitting display device is reinforced by the material the structure etc of the frame 110 the tape 120 is attached to a rear surface of the panel 100 relative to the direction in which light of the panel 100 is radiated the tape 120 allows the panel 100 to be attached and fixed to the frame 110 furthermore damage to the organic light emitting display device by an impact can be reduced by using the tape 120 the pcb 130 supplies signals and power to the panel 100 a flexible printed circuit board fpcb having flexibility may be used for the pcb 130.
