Abstract

The present invention discloses a display panel having a structure in which color filters are less likely to be damaged by heat treatment in a reducing atmosphere during the manufacture of a display device. The display panel (anode panel AP) includes a fluorescent area formed on a substrate, and an electrode (anode electrode) formed on the fluorescent area, wherein electrons emitted from an electron source penetrate the electrode and collide with the fluorescent area, causing The fluorescent area emits light to obtain a desired image, wherein a color filter and a color filter protective film are sequentially formed from a side of the substrate between the substrate and the fluorescent area.
