Embodiment 1

[0029] Hereinafter, this embodiment will be described with reference to the drawings.

[0030] figure 1 It is an overall configuration diagram of the active matrix organic EL display panel 100 of this embodiment. As shown in the figure, the display panel 100 is composed of a display area 11 provided with a plurality of pixels 10 arranged in a matrix of N rows and M columns on a substrate, and output to a scanning line connected to a group of pixels 10 arranged in the row direction. A scanning line driver 12 for scanning signals and a data line driver 13 for supplying data signals and power supply voltages to data lines and power supply lines connected to a group of pixels 10 arranged in the column direction are configured. On each pixel 10, an organic EL element emitting light in three primary colors of RGB is formed. A cathode 14 serving as a common electrode is formed on the entire surface of the display region 11 and is connected to an external circuit through a cathode l...

Embodiment 2

[0038] Figure 4 It is an explanatory diagram of the wiring layout of the embodiment.

[0039] In the present embodiment, a layout diagram for specifying the layout of wiring forming regions formed along the row direction of pixels is hypothetically provided, and a specific wiring forming region is focused on among a plurality of wiring forming regions. When the center is virtually returned to the layout diagram, wiring formation regions having the same type of wiring combination are overlapped. Three power supply lines V dd-G , V dd-R and V dd-B Arranged in the row direction as a group, the two scanning lines V sel As a group is laid out in the row direction. The basic form of the row direction wiring layout is to connect the three power lines V dd-G , V dd-R and V dd-B and two scan lines V sel They are respectively regarded as a group of layouts, and this basic form is laid out periodically and repeatedly. Therefore, the wiring layout of the wiring formation region...

Embodiment 3

[0043] Figure 5 It is an explanatory diagram of the wiring layout of Embodiment 3 of the present invention.

[0044] In this embodiment, a layout diagram specifying the arrangement and layout of wiring formation regions formed along the row direction of pixels is hypothetically provided, and a specific wiring formation region is focused on among a plurality of wiring formation regions. When the above-mentioned layout diagram is virtually returned to the center, wiring formation regions having the same type of wiring combination are overlapped and constituted.

Abstract

Provided is a wiring layout of electric power lines, which improves the aperture ratio of the pixel while forming pixels with the same pixel pitch. An electric-optical apparatus according to the present invention comprises multiple pixels (10) arranged in matrix including electro-optical devices driven by receiving electric power from an electric power supply circuit, wherein the aforementioned multiple pixels (10) make up multiple pixel groups formed of a series of pixels arrayed in at least one direction of the row direction and the column direction, and any of line forming regions (31, 32, 33, 34) is disposed between adjacent pixel groups of the aforementioned pixel groups, wherein the aforementioned line forming regions (31, 32, 33, 34) are formed with generally the same width.

Description

technical field [0001] The present invention relates to a wiring layout suitable for an electro-optical device including an electro-optical element. Background technique [0002] Since the organic EL element is a current-driven self-luminous element, it has the advantages of low power consumption, high viewing angle, and high contrast without the need for a backlight, and has been valued in the development of flat panel displays. An organic EL element is an electro-optical element with a light-emitting layer installed between an anode and a cathode. Since a positive bias current is supplied between the two electrodes, holes injected from the anode and electrons injected from the cathode are recombined at the time of recombination. energy to shine by itself. Therefore, in order to make the organic EL element emit light, it is necessary to supply power from an external circuit. [0003] In the conventional active-matrix-driven display panel for color display, for example, in...
