Organic light emitting display device and method of manufacturing the same

A method of manufacturing a light emitting display device, the method comprising:

• providing a first substrate having a first interior surface;
• forming an array of organic light emitting units on the first interior surface, the array having a top surface facing away from the first substrate;
• placing a second substrate over the first substrate and the array, the second substrate having a second interior surface, which faces the first substrate;
• interconnecting the first and second substrates with a plurality of side walls, thereby forming an enclosed space;
• and
• prior to interconnecting, forming a desiccant layer in a place to be enclosed within the enclosed space, the desiccant layer comprising a desiccant, a binder, a selective light absorber, and at least one of a metal oxide and a metal salt, wherein the at least one of the metal oxide and the metal salt is in a particulate form having an average particle diameter of about 100 nm or less, and wherein the desiccant layer is substantially transparent with respect to visible light.

A method of displaying a visable image, comprising:

• providing a light emitting display device comprising:
• a first substrate having a first interior surface,
• an array of light emitting units formed on the first interior surface, the array having a top surface facing away from the first substrate,
• a second substrate placed over the first substrate and the array, the second substrate having a second interior surface, which faces the first substrate, and
• a desiccant layer placed between the first and second substrates, the desiccant layer comprising a desiccant, a binder, a selective light absorber, and at least one of a metal oxide and a metal salt, wherein the at least one of the metal oxide and the metal salt is in a particulate form having an average particle diameter of about 100 nm or less, and wherein the desiccant layer is substantially transparent with respect to visible light;
• and
• stimulating the device to emit visible light from at least part of the light emitting units, thereby displaying a visible image on at least one of the first and second substrates.
