Abstract: The invention provides for the efficient use a substrate region in a liquid crystal device with built-in driving circuits which simultaneously drives a plurality of data lines, etc. One of substrates used for the liquid crystal device may include a plurality of latch circuits for sequentially outputting transfer signals, buffer circuits for outputting sampling-control signals via signal lines by performing wave shaping on the transfer signals input via wires, and sampling switches for sampling, in accordance with the sampling-control signals, video signals supplied to video-signal lines, and for supplying the sampled signals to the corresponding data lines. The buffer circuits each comprise inverters connected in series in three stages in a direction in which the data lines extend, and the inverter in each stage comprise seven inverters connected in parallel in a direction intersecting the extended direction of the data lines.

Abstract: An orthopedic computer mouse which can be translated over a support surface, the mouse adapted for supporting the hand in the “physiological position” or “position of function”. The proposed shape was obtained from a mold of the human hand, and the mold was realized in the “position of function.” This position forces the user's hand to be placed in a position of function, thus eliminating the possibility of diseases. The present invention provides an orthopedic computer mouse which is “innocuous,” i.e., a computer mouse which has no adverse effect on, or which is harmless to the user.
