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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
174 words
A display apparatus, comprising: 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 a first outer lead connected to the display device, a second outer lead connected to the unit substrate, an inner lead connected to the device circuit unit, a plurality of conductors connecting the leads, and an insulating substrate covering the conductors, wherein: a part of the film carrier connecting the display device and the drive circuit unit is provided with a first and a second blank portion where the insulating substrate is locally removed to expose the conductors, the second outer lead connected to the unit substrate extends in a direction perpendicular to an extension direction of the first outer lead connected to the display device, and the first and second blank portions are disposed in two elongated rows in a direction perpendicular to the extension direction of the first outer lead connected to the display device.
