Abstract: A light-emitting device can be folded in such a manner that a flexible light-emitting panel is supported by a plurality of housings which are provided spaced from each other and the light-emitting panel is bent so that surfaces of adjacent housings are in contact with each other. Furthermore, in the light-emitting device, in which part or the whole of the housings have magnetism, the two adjacent housings can be fixed to each other by a magnetic force when the light-emitting device is used in a folded state.

Abstract: A novel, highly convenient or reliable functional panel is provided. A novel, highly convenient or reliable method for manufacturing a functional panel is provided. The functional panel includes a first base; a second base having a region overlapping with the first base; a bonding layer that bonds the first base to the second base; and an insulating layer in contact with the first base, the second base, and the bonding layer. With this structure, an opening which is formed easily in a region where the bonding layer is in contact with the first base or the second base can be filled with the insulating layer, which can prevent impurities from being diffused into the functional layer located in a region surrounded by the first base, the second base, and the bonding layer that bonds the first base to the second base.

Abstract: To provide a liquid crystal display device which can perform image display in both modes: a reflective mode where external light is used as an illumination light source; and a transmissive mode where a backlight is used. In one pixel, a region where incident light through a liquid crystal layer is reflected to perform display (reflective region) and a region through which light from the backlight passes to perform display (transmissive region) are provided, and image display can be performed in both modes: the reflective mode where external light is used as an illumination light source; and the transmissive mode where the backlight is used as an illumination light source. In addition, two transistors connected to respective pixel electrode layers are provided in one pixel, and the two transistors are separately operated, whereby display of the reflective region and display of the transmissive region can be controlled independently.

Abstract: A display panel includes a flexible substrate, a first display region, a second display region, and a third display region. The first display region has a quadrangle outline and includes a first side and a second side forming a first corner portion of the outline. The second display region is in contact with the first side and the width of the second display region in a direction parallel to the first side coincides with the length of the first side. The third display region is in contact with the second side and the width of the third display region in a direction parallel to the second side coincides with the length of the second side. The substrate includes a notch portion corresponding a region facing the first display region with the first corner portion provided therebetween.
