Abstract

A liquid crystal display monitor includes a liquid crystal display module having a liquid crystal display panel and an illuminating device fixed between first and second frames. The rear surface of the second frame is provided with a tapped hole engaging with a screw, and a thickness of the second frame in the vicinity of the tapped hole is greater than that of the remainder of the second frame. The illuminating device includes plural line light sources behind the panel and a reflector behind the light sources. The reflector is shaped to have portions protruding toward the panel between the light sources and to have portions convex toward the second frame, and the tapped hole is provided in portions of the second frame corresponding to the portions of the reflector protruding toward the panel.

Claims

1. A liquid crystal display monitor, comprising:

a liquid crystal display module including a first frame, a liquid crystal display panel having a liquid crystal layer sandwiched between a pair of substrates, an illuminating device disposed behind said liquid crystal display panel, and a second frame for arrangement in the order named, with said first frame and said second frame for fixing said liquid crystal display panel and said illuminating device therebetween in cooperation with each other;

a housing having a mounting structure facing a rear surface of said second frame for mounting said liquid crystal display panel to said housing, said mounting structure being provided with at least one hole for passing at least one screw therethrough for affixing said liquid crystal display panel to said mounting structure; and

said rear surface of said second frame being provided with at least one tanned hole for engagement with a corresponding one of said at least one screw, and a thickness of said second frame in the vicinity of said at least one tapped hole being greater than a thickness of the remainder of said second frame, wherein said illuminating device comprises a plurality of line light sources arranged behind said liquid crystal display panel and a reflector disposed behind said plurality of line light sources, with said reflector being shaped to have portions protruding toward said liquid crystal display panel between said plurality of line light sources and portions convex toward said second frame behind said plurality of line light sources, and with said at least one tapped hole being provided in portions of said second frame corresponding to said portions of said reflector protruding toward said liquid crystal display panel.

2. The liquid crystal display monitor according to claim 1, wherein said first frame is provided with an opening for exposing at least a central area of one of said pair of substrates.
