Title:
アクティブマトリクス型EL表示装置及び電子機器
Document Type and Number:
Japanese Patent JP4906022
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a display device with a good balance between colors of EL elements and a good balance in emission intensity, which is capable of displaying brightly-hued images. SOLUTION: The greater current the pixel needs to be passed in the EL element, the greater the width of pulled-around wire through which voltage or current is to be supplied to the element concerned. With this, the greater current the pixel needs, the smaller the wiring resistance gets of the pulled- around wire through which voltage or current is to be supplied to the element concerned. When the wiring resistance gets small, fall of potential gets small in the pulled-around wire, therefore, it becomes possible to make larger current to be passed through the EL element. In addition, since space for pulled-around wire is limited in an actual panel, the rate of width of the wire is changed for each color, and that is how balancing is made on current flowing on the EL element for each color.
