Embodiment Construction

[0063] Next, an embodiment of the light-emitting device of the present invention will be described.

[0064] As shown in FIG. 4 , the structure of the light-emitting device 1 of this embodiment is: a plurality of scanning lines 101, a plurality of data lines 102 extending in a direction intersecting with the scanning lines 101, and a plurality of data lines 102 extending in parallel with the data lines 102 are respectively wired. A power cord 103 is used for the bar display.

[0065] A pixel region A is provided at the intersection of the scanning line 101 and the data line 102 .

[0066] A data-side driver circuit 104 having a shift register, a level shifter, a video line, and an analog switch is connected to the data line 102 . A scanning-side driver circuit 105 including a shift register and a level shifter is connected to the scanning line 101 .

[0067] When on the pixel area A, the scanning signal is supplied to the switching thin film transistor 122 of the gate throug...

Abstract

The invention provides a light-emitting device and an electronic apparatus, which are capable of preventing reduction of the amount of current flowing through light-emitting elements and which have an excellent display characteristic. Cathode wiring lines connected to a cathode are provided to surround an effective area outside the effective area where a plurality of pixels having light-emitting elements are provided. First to third power source lines connected to pixel electrodes are provided between the cathode wiring lines and the effective area.

Description

[0001] This application is a divisional application of the invention patent application with the application number 03138671.7, the application date is May 26, 2003, the applicant is Seiko Epson Co., Ltd., and the invention name is light-emitting device and electronic instrument. technical field [0002] The present invention relates to a light emitting device and an electronic device using the same. Background technique [0003] In recent years, an organic EL (electroluminescent) 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 counter electrode has attracted attention (for example, refer to JP-A-5-3080 Bulletin). [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 ...
