Patent ID: 7898614

Claim:
A liquid crystal display module comprising: a liquid crystal display panel; a backlight device arranged on a back surface of the liquid crystal display panel, the backlight device being constituted of a light guide plate and a reflection sheet arranged on a back surface of the light guide plate; a flexible printed circuit board having one end thereof mounted on a surface of the liquid crystal display panel and an other end thereof disposed in an overlapping relation with respect to a back surface of the reflection sheet so that one surface of the other end of the printed circuit board faces one portion of the back surface of the reflection sheet; an insulation sheet without wiring formed directly thereon is arranged between the one surface of the other end of the flexible printed circuit board and the back surface of the reflection sheet so as to at least enable contact between the insulation sheet and the one surface of the other end of the flexible printed circuit board; and at least one LED is provided on a portion of the one surface of the other end of the flexible printed circuit board so as to face an edge of the light guide plate and to be adjacent to an edge of the reflection sheet and an edge of the insulation sheet; wherein from the back surface of the light guide plate, the reflection sheet, the insulation sheet, and another portion of the other end of the flexible printed circuit board are arranged in this order; wherein the insulation sheet is arranged in an overlapping relation to the one surface of the other end of the flexible printed circuit board and at least the one portion of the back surface of the reflection sheet in a state that the insulation sheet extends over another portion of the back surface of the one surface of the reflection sheet which adjoins the one portion thereof beyond an edge of the other end of the flexible printed circuit board; and wherein the insulation sheet extends beyond the edge of the one surface of the other end of the flexible printed circuit board in overlapping relation with the back surface of the reflection sheet without extending to an edge of the reflection sheet in the extension direction of the reflection sheet from the at least one LED.
