A liquid crystal display apparatus (100) comprises light source modules (1) arranged at upper and lower edges, a light guide plate (2) arranged between the light source modules (1), a rear plate (3) arranged on the rear side of the light source modules (1) and the light guide plate (2), a fan mounting plate (4) arranged on the rear side of the rear plate (3), and a cooling fan (5) mounted on the fan mounting plate (4). The rear plate (3) is provided with projections (3a) which project toward the rear surface side of the light source modules (1). A cooling air passage (11) is formed between the fan mounting plate (4) and the rear plate (3). The fan mounting plate (4) is provided with L-shaped bent portions (4a) corresponding to the shape of the projections (3a) at the upper and lower end edges of the fan mounting plate (4) so that the surface area of the projections (3a) in contact with the air flow is increased to thereby enhance the cooling efficiency of the projections (3a). |
