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 optical device with less influence of stray light is provided. The optical device is thin and includes a half mirror, a first lens, a retardation plate, a reflective polarizing plate, and a second lens. In the optical device, a geometric phase lens which has negative and positive refractive power is used as the first lens, whereby images can be focused after magnified optically. Thus, the optical device can have a wide viewing angle. In the case where stray light occurs due to birefringence of an optical material, negative refractive power of the first lens can prevent the stray light from being focused on the eye direction. Accordingly, image degradation recognized due to stray light can be prevented.
