<P>PROBLEM TO BE SOLVED: To prevent reduction in brightness due to expansion/contraction of a reflection sheet. <P>SOLUTION: The liquid crystal display device includes: a reflection sheet 30 which is made of a material having a thermal expansion coefficient different from that of an LED substrate 20, and overlapped on the surface on which a plurality of light-emitting diodes 18 of the LED substrate are mounted; and a fixing member 38 and a holding member 40 for mutually mounting both members by penetrating them through the reflection sheet 30 and the LED substrate 20. The reflection sheet 30 includes: a hole 34 for fixing, through which the fixing member 38 is passed; a hole 36 for holding, through which the holding member 40 is passed; and a plurality of LED holes 32 inside which the plurality of the light-emitting diodes 18 are disposed, respectively. Holding of the reflection sheet 30 by the holding member 40 has a higher degree of freedom of movement in the direction along the surface of the reflection sheet 30 than fixing of the reflection sheet 30 by the fixing member 38. The LED hole 32 located at a position far from the hole 34 for fixing is larger than the LED hole 32 located at a position close to the hole 34 for fixing. <P>COPYRIGHT: (C)2012,JPO&INPIT |
