摘要： A backlight unit includes a lower frame comprising an opening; a light source arranged in the opening; a light guide plate arranged in the opening; and an upper frame arranged above the lower frame. The unit is so arranged that if one side of a projection (e.g., in the upper frame) is made in contact with one side of a hole (e.g. in the lower frame), then the first side end portion on the first overall end of the side surface of the upper frame is located approximately in the same plane with a first side end portion on the first overall end of the side surface of the lower frame, and the second side end portion on the second overall end of the side surface of the upper frame extends beyond the second side end portion on the second overall end of the side surface of the lower frame.

摘要： Problems to be SolvedProvided is a backlight unit capable of maintaining its outermost size of the plane even when a horizontal misalignment occurs in the fixation of the upper frame and the lower frame during assembling or transportation.Solution:A backlight unit includes a lower frame defining an opening portion in its upper portion, a light source arranged in the opening portion, a light guide plate arranged in the opening portion for guiding light from the light source, and an upper frame arranged at the opening portion side of the opening portion and having a window portion capable of transmitting light from the light guide plate. The lower frame and the upper frame are engagingly fixed at an engaging portion having a projecting portion integrally arranged on a side surface of one side surface and a rib portion defining a hole portion extending from an another side surface to the one side surface and to which the projecting portion can be engaged with. When viewed from a side, a lower portion of the side surface of the upper frame and an upper portion of the side surface of the lower frame are in contact with each other and the width of the hole portion is larger than the width of the projecting portion. When one side end portion of the projecting portion is made in contact with one side end portion of the hole portion, the side surface of the upper frame is located approximately on the same plane with the other side end portion of the side surface of the lower frame, and the other side end portion of the upper frame is located outer side than the other side end portion of the side surface of the lower frame.
