Abstract: To reduce the manufacturing cost of a display device using a micro LED as a display element. To manufacture a display device using a micro LED as a display element in a high yield. Employed is a method for manufacturing a display device, including: forming a plurality of transistors in a matrix over a substrate (800), forming conductors (21, 23) electrically connected to the transistors over the substrate (800), and forming a plurality of light-emitting elements (51) in a matrix over a film (927). Each of the light-emitting elements (51) includes electrodes (85, 87) on one surface and the other surface is in contact with the film (927). The conductors (21, 23) and the electrodes (85, 87) are opposed to each other. An extrusion mechanism (929) is pushed out from the film (927) side to the substrate (800) side so that the conductors (21, 23) and the electrodes (85, 87) are in contact with each other, whereby the conductors (21, 23) and the electrodes (85, 87) are electrically connected to each other.

Abstract: An angle adjustment device capable of being kept at a desired angle is provided. The angle adjustment device can fix and keep the relative positions of the first base component and the second base component, and a support with a combination of the angle adjustment device and components such as a flat plate can keep the entire body in a shape opened on a plane, a folded shape, a shape kept at a desired angle, or the like. In addition, the angle adjustment device can make a bending movement in one direction, which prevents bending in a reverse direction. Therefore, it is possible to prevent an accidental bending movement of an apparatus including the angle adjustment device to prevent breakage or the like of the apparatus.
