Patent ID: 8615871

Claim:
A liquid crystal display apparatus comprising a liquid crystal display panel, and a plurality of flexible printed circuit substrates which is fixed on the liquid crystal display panel by thermo-compression bonding, wherein the circuit substrate comprises wiring electrodes arranged in a first direction, and two of first positioning marks which are formed at both sides of an arrangement of the wiring electrodes in the first direction; the liquid crystal display panel comprises electrodes arranged at positions corresponding to the wiring electrodes, and two of second positioning marks formed at positions corresponding to the first positioning marks; each of the first positioning mark has a stepped portion formed to protrude outward from an arrangement of the electrodes of the liquid crystal display in the first direction; and the first positioning marks and the second positioning marks are formed so that the wiring electrode of the circuit substrate and the electrodes of the liquid crystal display will be connected at predetermined positions after the thermo-compression bonding when quantities of protrusions of the stepped portions of the first positioning marks from the second positioning marks in both sides in the first direction become substantially equal before the thermo-compression bonding.
