Abstract
Abstract A liquid crystal apparatus is constituted by a display device for data display, a drive circuit unit for driving the display device, a unit substrate for supplying electric signals to the drive circuit unit, and a tape-form film carrier comprising an insulating substrate and a conductor covered with the insulating substrate for connecting the display device, the drive circuit unit and the unit substrate. A part of the film carrier is provided with a blank portion where the insulating substrate is locally removed to absorb a stress applied to the film carrier. A unit substrate constituting the drive circuit unit is screwed to a supporting member so as to allow a movement thereof relative to the supporting member by use of a space regulating means surrounding the screw shank.
