## Abstract

The present invention provides an active matrix image display apparatus including an organic EL element capable of efficiently arranging a wiring pattern on an insulating substrate compared to the related art. The present invention provides a dummy region arranged at the outermost periphery of a display unit as a scanning line coupling region or a pitch conversion region. A power supply scanning line is commonly used by a pixel circuit of an odd-numbered line and a pixel circuit of a following even-numbered line.

## Claims

### Claim 1

An image display apparatus, comprising:
a plurality of pixel circuits arranged in a matrix form in a pixel region of a display unit;
a plurality of output lines comprising first output lines and second output lines, where each of the plurality of output lines is connected to at least one of the plurality of pixels circuits and the second output lines are grouped into second-output-units, each second-output-unit comprising n≧2 ones of the second output lines that are directly electrically connected to each other;
an output line drive circuit that is an integrated circuit for selectively introducing a first output signal severally to the first output lines and a second output signal severally to second-output-units,
wherein the output line drive circuit is mounted on the insulating substrate and is connected to the plurality of output lines by a output-line-connection wiring pattern formed on the insulating substrate, and
wherein the output-line-connection wiring pattern comprises first connection lines and second connection lines arranged such that:
each of the first connection lines corresponds to one of the first output lines and each respective first connection line is connected at a first end to a corresponding terminal of the output line drive circuit and at a second end to the first output line to which the respective first connection line corresponds, and
each of the second connection lines corresponds to one of the second-output-units and each respective second connection line is connected at a first end to a corresponding terminal of the output line drive circuit and at a second end, in a coupling region, to each of the second output lines that are grouped into the second-output-unit to which the respective second connection line corresponds.

### Claim 2 (depends on 1)

The image display apparatus of claim 1,
wherein at least part of the coupling region is arranged in the pixel region.

### Claim 3 (depends on 1)

The image display apparatus of claim 1,
wherein a wiring width of each of the second connection lines is greater than a wiring width of any of the first connection lines.
