| Abstract: |
An information processing device and its system is provided in which a display unit (head mount display) is used and a user carries out an information processing operation while seeing a virtual display screen. Polycrystalline silicon using CGS is used for a semiconductor of a display element of a liquid crystal panel used in the head mount display, so that high speed driving is made possible. The display unit in which frame inversion made in a writing period (60 to 180 Hz) is connected to a control unit and an input operating unit, so that the user can carry out the information processing operation.

What is claimed is:
1. An information processing device comprising:
- a display unit comprising flat panel displays for a right eye and a left eye and being mounted on a head of a user;
- a control unit operationally connected to said display unit; and
- an input operating unit connected to said control unit,
- wherein each of said flat panel displays comprises a plurality of first thin film transistors, each having a channel formation region, arranged in a matrix for switching pixels and a driver circuit comprising second thin film transistors for driving said first thin film transistors, said first and second thin film transistors formed over a same substrate,
- wherein said display unit, said control unit and said input operating unit are adapted to be used by the same user, and
- wherein 90% or more of crystal lattices in crystal grain boundaries of the channel formation region have continuity.
