Abstract

The invention realtes to a light emitting substrate, manufacturing method thereof, and image display apparatus having the light emitting substrate. The light emitting substrate includes a light emitting layer which emits light in response to the bombardment of electrons. A novel rib structure including a pattern of wall-like ribs and sheet-like ribs prevents the collapse of ribs in a finely-pitched pixel layout of the light emitting substrate. A light shielding layer is formed on a substrate, and wall ribs are formed on the light shielding layer. Then, a positive photo paste is spread thereon and exposed to light and then developed, so that sheet ribs having side surfaces tilting toward openings of the light shielding layer are formed.

Description

technical field [0001] The present invention relates to a light-emitting substrate, a method of manufacturing the light-emitting substrate, and an image display device used in, for example, a television provided with a light-emitting substrate having a light-emitting layer that emits light in response to electrons bombarded thereon. Background technique [0002] Flat panel displays (FPDs), also known as flat screen displays, are well known and commercially available in several forms and applications. As examples of currently available flat panel displays that display images using light emission generated by bombardment of electrons, there are known plasma displays (PDPs) and field emission displays (FEDs). [0003] Some of these display devices may utilize a rib (partition wall) structure to separate discharge cells. In order to improve luminous efficiency in the rib structure, it is desirable to form the ribs to be raised to increase the surface area of ​​the fluorescent m...
