Abstract:
1. A substrate having a fluorescent member arranged on a pixel area in a plane of a surface of the substrate, wherein the fluorescent member comprises a first fluorescent member that emits light in response to being irradiated with an electron arranged in the pixel area, and a second fluorescent member that emits light in response to being irradiated with an electron having a gamma value that is smaller than a gamma value of the first fluorescent member and arranged at a peripheral of the first fluorescent member within the pixel area, wherein the first fluorescent member has a current density area where the first fluorescent member is higher in luminance than the second fluorescent member, and the second fluorescent member has a current density area where the second fluorescent member is higher in luminance than the first fluorescent member.
