## Abstract

A liquid crystal display device (LCD) capable of avoiding damage due to external strain and a mobile communication unit using the same are disclosed. The LCD comprises a glass substrate 5 on one surface of which an LCD driver IC 11 is mounted by the COG (Chip On Glass) technique. A metallic light shielding plate 16 having a drawing processed portion 17 is mounted by way of a double-coated tape 16 on the other surface of the glass substrate 5 opposite to the surface on which the LCD driver IC 11 is mounted.

## Claims

### Claim 1

A liquid crystal display device comprising a pair of glass substrates adhered to each other interposing a liquid crystal between them, characterized in that:
a driving IC for driving and controlling the liquid crystal display device is mounted on one surface of one of the glass substrates and a metallic light shielding plate for shielding external light is disposed on the other surface of the one glass substrate.

### Claim 2 (depends on 1)

A liquid crystal display device of claim 1, wherein a drawing processed portion is formed in the light shielding plate in order to improve rigidity of the light shielding plate.

### Claim 3 (depends on 1)

A liquid crystal display device of claim 1, wherein the light shielding plate is installed by way of an adhesive layer on the surface of the one glass substrate opposite to the surface on which the driving IC is mounted.

### Claim 4 (depends on 2)

A liquid crystal display device of claim 2, wherein the drawing processed portion is formed in accordance with the shape of the driving IC.

### Claim 5 (depends on 1)

A liquid crystal display device of claim 1, wherein the driving IC is mounted on the one surface of the glass substrate by way of an adhesive layer by the COG technique.

### Claim 6 (depends on 1)

A mobile communication unit comprising the liquid crystal display device of claim 1.

### Claim 7 (depends on 2)

A liquid crystal display device of claim 2, wherein the light shielding plate is installed by way of an adhesive layer on the surface of the one glass substrate opposite to the surface on which the driving IC is mounted.

### Claim 8 (depends on 2)

A mobile communication unit comprising the liquid crystal display device of claim 2.

### Claim 9 (depends on 3)

A mobile communication unit comprising the liquid crystal display device of claim 3.

### Claim 10 (depends on 4)

A mobile communication unit comprising the liquid crystal display device of claim 4.

### Claim 11 (depends on 5)
