Abstract: An electronic device has a structure in which two portions between which a bent portion of a display panel is positioned are each fixed to a housing. The electronic device takes two forms of a form in which the display panel is opened and a form in which the display panel is folded in three. The electronic device includes a mechanism for sliding two housings parallel to each other. The display panel is changed in shape so that a portion where a display surface of the display panel is convexly curved and a portion where the display surface of the display panel is concavely curved in the folded state move in directions parallel and opposite to each other. At this time, the two portions of the display panel which are supported by the housings are slid while their display surfaces maintain a state parallel to each other.

Abstract: A high-resolution display device is provided. The display device includes a plurality of light-emitting units emitting light of different colors. The light-emitting unit has a microcavity structure and intensifies light with a specific wavelength. In the light-emitting units emitting light of different colors, reflective layers with different thicknesses are formed, an insulating layer is formed to cover the reflective layers, and then a top surface of the insulating layer is subjected to planarization treatment, whereby an insulating layer with different thicknesses is formed. After that, light-emitting elements emitting white light are formed over the planarized top surface of the insulating layer to overlap with the respective reflective layers, whereby the light-emitting units that intensify different colors due to different optical path lengths are separately formed.
