## Abstract

An optical module has a support, an optical film and a buffer. The optical film has a protrusion on one edge thereof. The buffer is disposed on the support and has a corresponded notch to accommodate the protrusion.

## Claims

### Claim 1

An optical module, comprising:
a support having a sidewall, wherein the support further comprises a pedestal and a bottom board;
an optical film disposed on the support and having a protrusion on one edge thereof; and
a buffer, disposed on the support, having a corresponding notch to accommodate the protrusion, wherein the buffer surrounds the optical film and the sidewall surrounds the buffer and the optical film.

### Claim 2 (depends on 1)

The optical module as claimed in claim 1, wherein the support has a generally uniform thickness.

### Claim 3 (depends on 1)

The optical module as claimed in claim 1, wherein the support is a flat plank.

### Claim 4 (depends on 1)

The optical module as claimed in claim 1, wherein the support is a frame.

### Claim 5 (depends on 1)

The optical module as claimed in claim 1, wherein cross-section of the support is a rectangle, an L shape, or a ladder shape.

### Claim 6 (depends on 1)

The optical module as claimed in claim 1, wherein the buffer comprises a plurality of disconnected portions, and the notch is constructed of two adjacent disconnected portions.

### Claim 7 (depends on 1)

The optical module as claimed in claim 1, wherein the buffer comprises a sidewall, and the notch is formed on the sidewall of the buffer.

### Claim 8 (depends on 1)

The optical module as claimed in claim 1, wherein the buffer comprises a top surface, and the notch is formed on the top surface of the buffer.

### Claim 9 (depends on 1)

The optical module as claimed in claim 1, wherein the buffer comprises a bottom surface, and the notch is formed on the bottom surface of the buffer.

### Claim 10 (depends on 1)

The optical module as claimed in claim 1, further comprising an adhesion layer interposed between the support and the buffer.

### Claim 11 (depends on 1)

The optical module as claimed in claim 1, further comprising a light shielding material configured on the buffer.

### Claim 12 (depends on 2)

The optical module as claimed in claim 2, further comprising a light guide, wherein the total thickness of the light guide and the optical film is greater than or equal to the thickness of the support.

### Claim 13 (depends on 3)

The optical module as claimed in claim 3, further comprising a light guide, wherein the total thickness of the light guide and the optical film is greater than or equal to the thickness of the support.

### Claim 14 (depends on 4)

The optical module as claimed in claim 4, further comprising a light guide, wherein the total thickness of the light guide and the optical film is greater than or equal to the thickness of the support.

### Claim 15 (depends on 1)

The optical module as claimed in claim 1, further comprising a light guide, wherein the total thickness of the light guide and the optical film is greater than or equal to the thickness of the support.

### Claim 16 (depends on 1)

A liquid crystal display panel, comprising the optical module as claimed in claim 1.

### Claim 17

An optical module, comprising:
a support having a sidewall;
an optical film disposed on the support and having a protrusion on one edge thereof; and
a buffer, disposed on the support, having a corresponding notch to accommodate the protrusion, wherein the buffer surrounds the optical film and the sidewall surrounds the buffer and the optical film, wherein the buffer comprises a plurality of disconnected portions, and the notch is constructed of two adjacent disconnected portions.
