ELECTRON SOURCE, METHOD OF MANUFACTURE THEREOF, AND DISPLAY DEVICE

Title:

ELECTRON SOURCE, METHOD OF MANUFACTURE THEREOF, AND DISPLAY DEVICE

Document Type and Number:

WIPO Patent Application WO/2001/026128

Kind Code:

A1

Abstract:

A thin-film electron source comprises a plurality of electron source elements, each including a laminate of a lower electrode (11), an insulating layer (12) and an upper electrode (13) formed in that order; and a plurality of buses for applying driving voltage to the upper electrode (13) of those in a first direction of the electron source elements. Each of the buses is composed of a thin-film electrode (15) connected electrically with the upper electrode (13), and a thick-film electrode (16) provided on the thin-film electrode (15) and being thicker than the thin-film electrode (15). This structure prevents the increase in resistance of the power buses for applying driving voltage to the electronic source elements and the damage to the upper electrodes (13) in the electron emission part.
