Abstract: A novel display panel that is highly convenient, useful, or reliable is provided. The display panel includes a display region, a first support, and a second support, the display region includes a first region, a second region, and a third region, the first region and the second region each have a belt-like shape extending in one direction, and the third region is sandwiched between the first region and the second region. The first support overlaps with the first region and is less likely to be warped than the third region, and the second support overlaps with the second region and is less likely to be warped than the third region. The second support can pivot on an axis extending in the one direction with respect to the first support.

Abstract: A display device with high display quality and low power consumption is provided. In the display device, a first transistor, a second transistor, a first conductive layer, and a light-emitting diode package are included in a pixel, and then the light-emitting diode package includes a first light-emitting diode, a second light-emitting diode, a second conductive layer, a third conductive layer, and a fourth conductive layer. One of a source and a drain of the first transistor is electrically connected to the first light-emitting diode through the second conductive layer. One of a source and a drain of the second transistor is electrically connected to the second light-emitting diode through the third conductive layer. The first conductive layer supplied with a constant potential is electrically connected to the other electrodes of the first and second light-emitting diodes through the fourth conductive layer.

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.
