Liquid crystal display device having impact resistant light guide and housing

摘要

A liquid crystal display device including a liquid crystal display panel, an illumination unit including a light-conducting plate having a protrusion protruded from a side surface of the light-conducting plate, and a housing having a bottom plate and a casing provided onto a bottom plate peripheral area for holding the light-conducting plate. A depression portion is formed to the casing of the housing. An inside of the bottom plate peripheral area is processed from roots of the end surfaces along the end surfaces so that a first slit which continues to the end surfaces is formed. The casing in a position separated from the end surfaces with a predetermined interval and an inside of the bottom plate peripheral area in this position are processed so that a second slit is formed. A portion of the housing composed of a part of the casing sandwiched between the first slit and the second slit and the bottom plate is supported to the housing in a manner of a fixed beam with respect to a load in the locating direction.
