Patent ID: 8520157

Claim:
An active matrix display device, wherein one end of a plurality of auxiliary capacitance bus lines on a predetermined side is respectively connected through contact holes to at least one of CS trunk wiring lines of a CS trunk wiring group formed in such a way as to extend in a direction orthogonal to the direction in which said auxiliary capacitance bus lines extend in a region adjoining an active area of a display region on said one side of the direction in which said auxiliary capacitance bus lines extend; the other end of said auxiliary capacitance bus lines is respectively connected through contact holes to at least one CS trunk wiring line of a CS trunk wiring group formed in such a way as to extend in a direction orthogonal to the direction in which said auxiliary capacitance bus lines extend in an area adjoining said active area on said other side of the direction in which said auxiliary capacitance bus lines extend; and an auxiliary capacitance voltage is applied to each of said auxiliary capacitance bus lines through said connected CS trunk wiring line, and wherein a feed portion, which is a current flow path segment of said at least one auxiliary capacitance bus line from said active area to a point of connection on at least one CS trunk wiring line in at least one of said CS trunk wiring groups, originates on said active area side, passes through a region on an inner side of said point of connection, the inner side being the side of said active area with respect to each of said CS trunk wiring groups, is routed to a region on an outer side of said point of connection, and is connected to said point of connection.
