Embodiment 2

[0127] Next, Example 2 will be described. Figure 10 The layout of the display device of the shown embodiment 2 and figure 2 The main difference in the layout of the first embodiment shown is that at least a part of the common electrode wiring 12a overlaps with at least a part of the power supply lines 103R, 103G, and 103B provided around the active region 2a in plan view. The common electrode wiring 12a extends from the side on which the flexible substrate 5 is mounted to the side opposite to the side, and is respectively provided between two sides facing each other among the four sides constituting the outer periphery of the substrate 2 and the active region 2a, One common electrode wiring 12a is arranged to overlap the power supply line 103R, and the other common electrode wiring 12a is arranged to overlap at least a part of 103G and 103B.

[0128] FIG. 11 shows a sectional view corresponding to this. The common electrode wiring 12 a is made of a conductive film provided...

Abstract

The invention provides an electrooptical device and electronic apparatus. The electro-optical apparatus are capable of narrowing the frame region. A light-emitting power source wiring lines and second electrode wiring lines disposed around a first electrode region where first electrodes are arranged in a matrix on a substrate, the light-emitting power source wiring lines being connected to the first electrodes, the second electrode wiring lines being connected to a second electrode, a functional layer being interposed between the first electrodes and the second electrode, wherein the light-emitting power source wiring lines and the second electrode wiring lines are arranged such that at least some of the wiring lines overlap each other in plan view. In addition, the electronic apparatus has the electrooptical device.

Description

[0001] This application is a divisional application of the application number: 03140936.9, the name of the invention: electro-optic device and electronic instrument, and the application date: 2003.6.4. technical field [0002] The present invention relates to electro-optical devices and electronic instruments. Background technique [0003] In recent years, an organic EL (Electroluminescence) display device having a light-emitting element using an organic light-emitting material between a substrate on which a pixel electrode is formed and a common electrode (for example, refer to JP-A-5-3080) has attracted attention. . [0004] In an organic EL display device, a light-emitting element emits light by supplying a current to the light-emitting element. At this time, the luminance of the light emitting element is basically determined by the amount of current supplied. [0005] As described above, the luminance of the light-emitting element is basically determined by the current...
