ABSTRACT:
A liquid crystal apparatus in which an anisotropic conductive layer made of organic resin containing several electrically conductive particles having substantially identical particle sizes is disposed between lead electrodes of a liquid crystal device and the lead electrodes of a drive circuit board, thermocompression bonding being applied to make the electrically conductive particles in direct contact with both lead electrodes to allow both lead electrodes to be electrically connected with each other. Further, at least one of the lead electrodes of a common electrode in the liquid crystal device and of the circuit board corresponding to the common electrode includes a number of separated electrodes that are spaced apart, and the pitches and widths of the separated electrodes are in the range of .+-.30% around the average values for pitch and width for the separated electrodes.
