20080285290 | LIQUID CRYSTAL DISPLAY DEVICE - If a forced convection is generated by a cooling fan, there is generated a problem that a natural convection is prevented and a cooling effect in a region of the natural convection is lowered. The invention provides a structure in which an air flow generated by a forced convection does not come into contact with an air flow generated by a natural convection, by setting a partition all between a forced convection path in which the air flows on the basis of a forced convection generated by a cooling fan, and a natural convection path in which the air flows on the basis of a natural convection. Further, the partition wall is not provided near an upper end so as to draw in the air flowing through the natural convection path to a side of the forced convection path, thereby promoting the natural convection of the natural convection path. | 11-20-2008 |
