The structure of the present invention for achieving the above object is to provide a portable information processing device in which a lid casing having a liquid crystal display device attached thereto is openably and closably coupled to a main casing by a hinge mechanism. In a mounting structure of a liquid crystal display device, a front mounting portion is provided on a front side of a metal frame of the liquid crystal display device corresponding to a fixing portion of the lid housing to which the lid housing mounting portion of the hinge mechanism is fixed. The front mounting portion of the frame is overlapped with the lid housing mounting portion of the hinge mechanism and fixed together to the lid housing.

[0008]

Since the hinge mechanism of the lid housing is located near the outer periphery of the lid housing, and the front mounting portion of the liquid crystal display device is mounted at this position, the liquid crystal display device can be manufactured even if the lid housing is made thin. Deformation due to its own weight is prevented. The fixed part of the lid housing is
Since both the hinge mechanism and the liquid crystal display device also serve as fixing parts, the number of parts can be reduced and the cost can be reduced.
