  • Patent number: 11575109
    Abstract: A display device capable of reducing a non-display area includes a substrate hole surrounded by light emitting elements, and a moisture penetration preventing layer disposed between an inner dam surrounded by the light emitting elements and the substrate hole. Accordingly, it is possible to prevent damage to light emitting stacks caused by external moisture or oxygen. Since the substrate hole is disposed within an active area, a reduction in non-display area is achieved.
    Type: Grant

  • Patent number: 8802464
    Abstract: A method for fabricating a process substrate includes: providing a first substrate; providing a substrate and an auxiliary substrate; contacting the substrate and the auxiliary substrate with each other in a vacuum state, thereby forming micro spaces of a vacuum state between the substrate and the auxiliary substrate; and increasing a pressure at the outside of the contacted substrate and auxiliary substrate to attach the substrate and the auxiliary substrate to each other by a pressure difference between the micro spaces and the outside of the contacted substrate and auxiliary substrate.
