Display device

1. A display device, comprising:

a plurality of display panels, each of the plurality of display panels capable of displaying images independently;

a protection plate, which is disposed on a front surface of the plurality of display panels; and

a transparent adhesive, which covers a display surface of each of the plurality of display panels to adhere the display panels to the protection plate,

wherein each of the plurality of display panels includes:

a pair of substrates, on which plural wirings and plural electrodes are formed,

a driver circuit, which inputs signals to the plural wirings to drive the plural electrodes, and

a detection circuit, which detects an abnormality in at least one of a case where the signals are not output at a normal timing and a case where a final signal output from an internal shift register is not detected.

2. The display device according to claim 1 , wherein

the detection circuit is provided to each of the display panels independently, and wherein

when the detection circuit detects the abnormality, a control function stops inputting signals to the display panel in which the abnormality is detected.

3. The display device according to claim 2 , wherein

the control function includes a selecting function to selectively permit inputting of a predetermined signal to a display panel of the plurality of display panels, in which the abnormality is not detected.

4. The display device according to claim 3 , wherein

the display device is connected with a plurality of cameras for displaying images on the plurality of display panels, and wherein

the selecting function is configured to stop inputting the signals to the display panel in which the abnormality is detected, and to selectively input a predetermined image displaying signal, which is input from a camera of the plurality of cameras, to the display panel in which the abnormality is not detected.

5. The display device according to claim 1 , wherein

the display device further comprises a backlight and a frame, wherein

the backlight irradiates the plurality of display panels with light,

the backlight includes an irradiation region corresponding to the plurality of display panels, and

the frame is formed as an integral unit and contains the plurality of display panels and an optical member configuring the backlight.

6. The display device according to claim 5 , wherein

the frame is fixed to a peripheral portion of the protection plate.

7. The display device according to claim 5 , wherein

the backlight includes a plurality of irradiation regions, wherein each of the plurality of irradiation regions is configured to irradiate a respective one of the plurality of display panels with light, and wherein

the backlight has a plurality of lighting systems to turn on a light source, wherein each of the plurality of lighting systems corresponds to a respective one of the plurality of irradiation regions.

8. The display device according to claim 7 , wherein

when the signal output from the driver circuit to the plural wirings has the abnormality, a control function stops the lighting system for turning on the light source of the irradiation region corresponding to the display panel in which the abnormality is detected.

9. The display device according to claim 1 , wherein

the display panel is a horizontal electric field type panel.

10. The display device according to claim 1 , wherein

the display panels each include a polarizing plate which is attached to a front surface of the substrate, and the polarizing plate on the display surface is formed in one sheet and is disposed to connect each of the display panels.

11. The display device according to claim 10 , wherein

a light shielding member is disposed on ends of the display panels, between the display panels.
