## Abstract

Disclosed is a liquid crystal display device which can be used in a variety of situations and applications. The liquid crystal display device comprises: a first substrate comprising a first display region, a second display region, and a third display region wherein the first display region, the second display region, and the third display region are continuously formed; a second substrate having a form which fits the first substrate; and a liquid crystal interposed between the first substrate and the second substrate. The second display region is interposed between the first display region and the second display region. The second display region is curved, and the first display region and the second display region are substantially flat.

## Claims

### Claim 1

An electronic appliance comprising:
a battery;
a display panel, the display panel comprising:
a first flexible substrate over the battery;
an element layer over the first flexible substrate with a protective film therebetween; and
a second flexible substrate over the element layer;
a light-transmitting member; and
a wiring board connected to the display panel;
wherein the second flexible substrate is attached to the light-transmitting member with an adhesive layer,
wherein in a side view of the electronic appliance, the light-transmitting member comprises a flat region and a curved region extended from both ends of the flat region,
wherein the element layer and the protective film are provided along the flat region and the curved region,
wherein images or letters are displayed on the flat region and the curved region, and
wherein in a plan view of the electronic appliance, the battery and the wiring board are not overlapped with each other.

### Claim 2 (depends on 1)

The electronic appliance according to claim 1, wherein the protective film comprises an inorganic insulating material.
