Black matrix, flat panel display device and method for producing the same

A method for producing a black matrix of a flat panel display device, comprising:

• providing a substrate and producing a microstructure on a surface of the substrate located in a first plane;
• producing a light absorption layer on the microstructure;
• producing a microstructure layer on the light absorption layer;
• and
• producing a light reflection layer on the microstructure layer, wherein the microstructure layer is configured such that light incident on the light reflection layer in a direction perpendicular to the first plane is emitted out obliquely with respect to the first plane after the light is reflected by the light reflection layer, and
• wherein the light absorption layer covers only a part of a surface of the microstructure layer facing towards the surface of the substrate and the light reflection layer covers only a part of another surface of the microstructure layer facing away from the light absorption layer.

• and
• producing a light reflection layer on the microstructure layer,
• wherein the microstructure layer is configured such that light incident on the light reflection layer from a side of the light reflection layer away from the light absorption layer in a direction perpendicular to the first plane is emitted out obliquely with respect to the first plane after the light is reflected by the light reflection layer, and
• wherein the light absorption layer covers only a part of a surface of the microstructure layer facing towards the surface of the substrate and the light reflection layer covers only a part of another surface of the microstructure layer facing away from the light absorption layer.
