Title:
IMAGE DISPLAY DEVICE AND MANUFACTURE THEREOF
Document Type and Number:
Japanese Patent JPH0320941
Kind Code:
A
Abstract:

PURPOSE: To display a high-precision image on a large screen at a low cost by integrally forming modulating electrodes and surface conductive type electron emitting elements via an insulator.

CONSTITUTION: Surface conductive type electron emitting elements with less power consumption are used for an electron generating source. A line-shaped modulating electrode 32 group is formed on a glass substrate 31, and an insulator film 33 is formed on it. Element electrodes 35 and element wiring electrodes 34 are formed on the insulator film 33 at the high-precision mutual positional relationship required with modulating electrodes 32. An electron emitting section 36 formed between parallel element electrodes, e.g. 34-a and 34-b, maintains the high-precision positional relationship with the corresponding modulating electrode, and a large screen with no irregularity can be formed.
