Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 105 words
A matrix display apparatus comprising: a pair of substrates, at least one of which is translucent, a display medium that is placed between said pair of substrates and that modulates its optical characteristics in response to voltage that is applied, display electrodes that are formed on the inner surface of at least one of said pair of substrates, driving wires for the driving of said display electrodes, and repair wires for the repair of said driving wires, wherein said matrix display apparatus has a layered structure in which said driving wires are layered on and along said repair wires to sandwich an insulating film therebetween.
Claim 2
Dependent Claim 105 words
A matrix display apparatus comprising: a pair of substrates, at least one of which is translucent, a display medium that is placed between said pair of substrates and that modulates its optical characteristics in response to voltage that is applied, display electrodes that are formed on the inner surface of at least one of said pair of substrates, driving wires for the driving of said display electrodes, and repair wires for the repair of said driving wires, wherein said matrix display apparatus has a layered structure in which said driving wires are layered on and along said repair wires to sandwich an insulating film therebetween.
Claim 3
Dependent Claim 164 words
An active matrix display apparatus provided with a pair of substrates, at least one of which is translucent, a display medium that is placed between said pair of substrates and that modulates its optical characteristics in response to voltage that is applied, picture element electrodes arranged in matrix form on the inner surface of one of said pair of substrates; switching elements for driving the picture element electrodes, and driving wires that have scanning wires and signal wires connected to the switch elements, as well as picture element electrode driving wires that connect the switching elements and the picture element electrodes, wherein an electrically conductive light-proof film is layered on the outer portions of the picture element electrodes and on the driving wires to sandwich an insulating film therebetween, and divided into plural parts, and an area of the conductive light-proof film that is on the outer portions of the picture element electrodes and on the driving wires is coated with a protective film.
Claim 4
Dependent Claim 164 words
