Method of manufacturing flat panel displays
First Claim
1. A method of manufacturing a flat panel display, which comprises:
- preparing a substrate of a size determinative of the size of a display screen;
partially printing the substrate with a surface treating material to form a printed pattern of undercoats in an area encompassing a pattern of constituent elements that are to be formed on the substrate;
irradiating the undercoats with rays of light effective to remove or modify portions of the undercoats other than necessary portions thereof which eventually form the constituent elements, to thereby leave an effective pattern of the undercoats on the substrate, the effective pattern of the undercoats in a shape corresponding to the pattern of the constituent elements; and
selectively depositing on the undercoats a film material of a kind having a high propensity of being deposited on the undercoats than that on the substrate, to thereby form the constituent elements.

Abstract
To enable formation of a pattern of constituent elements, arranged in correspondence with an arrangement of cells in a display region, as desired or required with a minimized quantity of the film material, a method of manufacturing a flat panel display is provided which includes printing on a substrate a surface treating material capable of partially enhancing the wettability of the substrate, in a predetermined pattern sufficient to encompass the eventually formed pattern of constituent elements of the flat panel display. Undercoats made of the surface treating material so printed is then patterned by irradiation of light. Thereafter, utilizing the undercoats, a film material is thereafter selectively deposited on the substrate to thereby complete the predetermined pattern of the constituent elements.

-
preparing a glass substrate of a size determinative of the size of a display screen;
partially printing the glass substrate with a surface treating material to form a printed pattern of undercoats in an area encompassing a pattern of electrodes that are to be formed on the substrate;
irradiating the undercoats with rays of light effective to remove or modify portions of the undercoats other than necessary portions thereof which eventually form the electrodes, to thereby leave an effective pattern of the undercoats on the substrate, the effective pattern of the undercoats in a shape corresponding to the pattern of the electrodes; and
