ABSTRACT:
A liquid crystal display device characterized in that an illumination unit includes a substantially wedge-shaped light-guiding plate5being tilted such that plate thickness becomes thinner from one side edge toward the other side edge, a light source41disposed along the thicker plate surface of the light-guiding plate, lead wires43, 44of the light source, and a housing7that houses these parts, in which the light-guiding plate is installed such that a gap L2between the backside52of the light-guiding plate and the bottom wall of the housing becomes larger as the plate thickness becomes thinner, and a portion of the lead wires resides in the gap L2and the wires are arranged along the other side edge54of the light-guiding plate. Further, it is preferable that a circuit board11for driving a liquid crystal display panel2be attached on the backside of the housing to lie parallel with the liquid crystal display panel and a guide member7afor guiding connection of a main body side connector to a connector11aof the circuit board be formed on the housing. With this constitution, a smaller and slimmer liquid crystal display device can be provided where the lead wires are easily arranged, and connection to connectors is highly facilitated.
