CROSS-REFERENCE TO RELATED APPLICATIONS

This application is based upon and claims the benefit of priority from Japanese Patent Application No. 2019-114716, filed Jun. 20, 2019, the entire contents of which are incorporated herein by reference.

FIELD

Embodiments described herein relate generally to a liquid crystal display device.

BACKGROUND

Liquid crystal panels such as memory in pixel (MIP) liquid crystal have recently started to become widespread. The liquid crystal panels are excellent in low power consumption because their pixels each have a memory and an image can be displayed using video signals stored in the memory to display a still image or the like.

In a display device equipped with a liquid crystal panel, the liquid crystal panel may be connected to a controller that controls the liquid crystal panel, via a relay substrate or the like. The relay substrate and the controller may also be connected to each other via a plurality of cables such as flat flexible cables. In this case, the manufacturing process of the display device requires a step of connecting one end of a cable to the connector on the relay substrate side and connecting the other end of the cable to the connector on the controller side.

In the above display device, when the liquid crystal panel is to be turned on with part of the cable not connected due to an error in the step of connecting the cable to the connector, it may cause its lighting failure and may be damaged accordingly.
