Abstract

In a joint portion of a corner portion at which a raised portion of a side wall portion of a reflection sheet which is mounted on a back surface plate and a side wall portion of a side mold frame intersect each other, an end portion of the side mold frame is formed in a state that the end portion of the side mold frame overlaps the side wall portion of the reflection sheet. Due to such a constitution, a gap which is formed by a displacement of the reflection sheet is closed and hence, it is possible to suppress the intrusion of dusts into the inside of a liquid crystal display device.

Claims (10)

1. A liquid crystal display device comprising:

a liquid crystal display panel; and

a direct light backlight structural body which is arranged on a back surface of the liquid crystal display panel, wherein

the backlight structural body includes:

a plurality of fluorescent lamps which is arranged in parallel to each other between a trough-shaped back surface plate and a frame-shaped mold frame in a state that the plurality of fluorescent lamps faces the back surface plate in an opposed manner;

a side mold frame which is mounted on the back surface plate and covers electrode portions of the fluorescent lamps; and

a reflection sheet which is arranged between the back surface plate and the fluorescent lamps as well as between the back surface plate and the side mold frame, and

an end portion of the side mold frame includes an extending portion which is formed in a state that the extending portion extends to a position outside a side wall portion of the back surface plate and, at the same time, is bent along a raised portion of the reflection sheet.

2. A liquid crystal display device according to claim 1 , wherein the extending portion is integrally formed with the side mold frame using a formed body of a same resin material.

3. A liquid crystal display device according to claim 1 , wherein the side mold frame is arranged along two sides of the mold frame which face each other in an opposed manner.
