Abstract

To provide a display device that is suitable for increasing in size. To provide a display device in which display unevenness is suppressed. To provide a display device that can display an image along a curved surface. The display device includes two display panels, two plates, two stages, two driver circuits, two adjusting units, and a frame. Each display panel includes a display portion, an operating circuit portion, a terminal, an external electrode, a transparent portion, and a first portion and has flexibility. Each transparent portion includes a region transmitting visible light. The display panels are fixed so that transparent portions and parts of the display portions extend beyond the plates. The display portion of one of the two display panels overlaps with the transparent portion of the other display panel.

Claims (23)

1. A display device comprising:

a first unit comprising a first display portion over a first display panel, a first plate, a first stage, a first driver circuit, and a first adjusting unit;

a second unit comprising a second display portion over a second display panel, a second plate, a second stage, a second driver circuit, and a second adjusting unit; and

a frame,

wherein the first and second driver circuits are configured to output signals for driving their respective first and second display panels,

wherein the first and second adjusting units are independently configured to adjust positions and angles of their respective first and second stages and are fixed to the frame, and

wherein the first and second display panels are configured to form one continuous display area by contacting the first and second display panels to each other; wherein the first and second plates each comprise a convexly curved surface, and wherein a part of the first and a part of the second display panels extend beyond the first and second plates, respectively.

2. The display device according to claim 1 , further comprising a video signal divider and a video output unit,

wherein the video output unit is configured to output a video signal or an image signal to the video signal divider, and

wherein the video signal divider is configured to divide the video signal or the image signal into a plurality of signals and output the signals to the first and second driver circuits.

3. The display device according to claim 1 ,

wherein the first driver circuit is configured to adjust color tone and luminance of images or video that is to be displayed on the first display panel, and

wherein the second driver circuit is configured to adjust color tone and luminance of images or video that is to be displayed on the second display panel.

4. The display device according to claim 1 ,

wherein each of the first and second display portions comprises a plurality of pixels, and

wherein the plurality of pixels each comprise a transistor and a light-emitting element comprising a lower electrode, an upper electrode, and an EL layer between the lower electrode and the upper electrode.

5. The display device according to claim 4 ,

wherein each of the first and second display portions comprises an auxiliary electrode, and

wherein each of the auxiliary electrodes is in contact with the upper electrode in a region between adjacent lower electrodes in the plurality of lower electrodes.

6. The display device according to claim 1 , wherein the first and second display panels cover top surfaces, bottom surfaces, and the convexly curved surfaces of the first and second plates, respectively.

7. The display device according to claim 1 ,

wherein the first and second adjusting units are respectively under the first and second plates, and

wherein the first and second plates do not overlap with each other.
