## Abstract

A backlight assembly includes: lamps; lamp holders each holding at least one of opposite ends of a corresponding one of the lamps, the lamp holders being electrically connected with external electrodes of the lamps; and a lower frame formed to partially cover the lamp holders such that the lower frame is formed in one unified body with the lamp holders.

## Claims

### Claim 1

A backlight assembly comprising:
lamps;
lamp holders each holding at least one of opposite ends of a corresponding one of the lamps, the lamp holders being electrically connected with external electrodes of the lamps; and
a lower frame formed to partially cover the lamp holders such that the lower frame is formed in one unified body with the lamp holders,
wherein the lamp holders comprise: lamp clips for holding the lamps; supporters for supporting the lamp clips; and connectors for connecting the supporters at opposite ends of the supporters, respectively; and
wherein the lower frame comprises: a seat on which the lamp holders are seated; and movement preventing members formed in a unified body with the seat such that a portion of each lamp holder is interposed between the seat and a corresponding one of the movement preventing members.

### Claim 2 (depends on 1)

The backlight assembly according to claim 1, wherein each movement preventing member is formed to cover at least one of a corresponding one of the connectors and a corresponding one of the supporters.

### Claim 3 (depends on 1)

The backlight assembly according to claim 1, wherein the movement preventing members are formed to cover the lamp holders in regions where the connectors and the supporters cross each other.

### Claim 4

An assembling method of a backlight assembly, comprising:
preparing a lower frame formed to partially cover lamp holders such that the lower frame is formed in a unified body with the lamp holders; and
holding lamps in the lamp holders such that each lamp is held by a corresponding one of the lamp holders at at least one of opposite ends of the lamp;
wherein the step of preparing the lower frame comprises: preparing the lamp holders such that the lamp holders comprise lamp clips for holding the lamps, and supporters for supporting the lamp clips, and connectors for connecting corresponding ones of opposite ends of the supporters, respectively; arranging the lamp holders in an injection mold for the lower frame; and injecting a molten plastic resin into the injection mold, to mold the lower frame such that the lower frame is formed with movement preventing members; and
wherein each movement preventing member is formed to cover at least one of a corresponding one of the connectors and a corresponding one of the supporters.

### Claim 5

An assembly method of a backlight assembly, comprising:
preparing a lower frame formed to partially cover lamp holders such that the lower frame is formed in a unified body with the lamp holders; and
holding lamps in the lamp holders such that each lamp is held by a corresponding one of the lamp holders at at least one of opposite ends of the lamp;
wherein the step of preparing the lower frame comprises: preparing the lamp holders such that the lamp holders comprise lamp clips for holding the lamps, and supporters for supporting the lamp clips, and connectors for connecting corresponding ones of opposite ends of the supporters, respectively; arranging the lamp holders in an injection mold for the lower frame; and injecting a molten plastic resin into the injection mold, to mold the lower frame such that the lower frame is formed with movement preventing members; and
wherein the movement preventing members are formed to cover the lamp holders in regions where the connectors and the supporters cross each other.
