Patent ID: 7397450

Claim:
A display panel of an image display, which includes a plurality of data lines for transmitting a data signal corresponding to a video signal, a plurality of scan lines for transmitting a select signal, and a plurality of pixel circuits each of which is in a pixel region defined by two neighboring data lines and two neighboring scan lines, each said pixel circuit comprising: a display element for displaying an image corresponding to an amount of a current applied thereto; a first transistor having a capacitor coupled between a main electrode and a control electrode thereof, the first transistor being for outputting the current applied to the display element, the amount of the current corresponding to a voltage between the main electrode and the control electrode thereof; a second transistor whose control electrode is coupled to the control electrode of the first transistor, the second transistor being diode-connected; and a first switching element coupled to a main electrode of the second transistor, the first switching element being for delivering the data signal from a corresponding said data line to the second transistor in response to the select signal from a current said scan line, wherein channels of the first and second transistors are elongated in an elongation direction that is substantially parallel to the scan lines, and wherein the channels of the first transistors of the pixel circuits that are adjacent to each other in the elongation direction are aligned with each other along a first line, and the channels of the second transistors of the pixel circuits that are adjacent to each other in the elongation direction are aligned with each other along a second line that is parallel to and spaced from the first line.
