  • Patent number: 10727437
    Abstract: To realize a high-performance liquid crystal display device or light-emitting element using a plastic film. A CPU is formed over a first glass substrate and then, separated from the first substrate. A pixel portion having a light-emitting element is formed over a second glass substrate, and then, separated from the second substrate. The both are bonded to each other. Therefore, high integration can be achieved. Further, in this case, the separated layer including the CPU serves also as a sealing layer of the light-emitting element.

  • Publication number: 20200152673
    Abstract: There is provided a peeling method capable of preventing a damage to a layer to be peeled. Thus, not only a layer to be peeled having a small area but also a layer to be peeled having a large area can be peeled over the entire surface at a high yield. Processing for partially reducing contact property between a first material layer (11) and a second material layer (12) (laser light irradiation, pressure application, or the like) is performed before peeling, and then peeling is conducted by physical means. Therefore, sufficient separation can be easily conducted in an inner portion of the second material layer (12) or an interface thereof.

  • Patent number: 10629637
    Abstract: To provide a semiconductor device in which a layer to be peeled is attached to a base having a curved surface, and a method of manufacturing the same, and more particularly, a display having a curved surface, and more specifically a light-emitting device having a light emitting element attached to a base with a curved surface. A layer to be peeled, which contains a light emitting element furnished to a substrate using a laminate of a first material layer which is a metallic layer or nitride layer, and a second material layer which is an oxide layer, is transferred onto a film, and then the film and the layer to be peeled are curved, to thereby produce a display having a curved surface.

  • Patent number: 10607883
    Abstract: A semiconductor device having a semiconductor element (a thin film transistor, a thin film diode, a photoelectric conversion element of silicon PIN junction, or a silicon resistor element) which is light-weight, flexible (bendable), and thin as a whole is provided as well as a method of manufacturing the semiconductor device. In the present invention, the element is not formed on a plastic film. Instead, a flat board such as a substrate is used as a form, the space between the substrate (third substrate (17)) and a layer including the element (peeled layer (13)) is filled with coagulant (typically an adhesive) that serves as a second bonding member (16), and the substrate used as a form (third substrate (17)) is peeled off after the adhesive is coagulated to hold the layer including the element (peeled layer (13)) by the coagulated adhesive (second bonding member (16)) alone. In this way, the present invention achieves thinning of the film and reduction in weight.

  • Publication number: 20200043381
    Abstract: A plurality of display panels having a curved surface are placed in a limited space. Two, or three or more display panels are combined to form one display region having a T-shaped outer edge as one screen, and a driver can curve part of the display panel as appropriate so that the driver can see the screen easily. A first display panel or a second display panel has flexibility and includes a position adjustment function of curving an end portion. That is, by curving part of the display panel, the user can see the display panel easily. The in-car design can also be varied.

  • Patent number: 9793328
    Abstract: Failure light emission of an EL element due to failure film formation of an organic EL material in an electrode hole 46 is improved. By forming the organic EL material after embedding an insulator in an electrode hole 46 on a pixel electrode and forming a protective portion 41b, failure film formation in the electrode hole 46 can be prevented. This can prevent concentration of electric current due to a short circuit between a cathode and an anode of the EL element, and can prevent failure light emission of an EL layer.
