Abstract
The wide-angle emission filter includes a base matrix, a photoresist, and a colorant. The base matrix has a flat shape and including a transparent material. The base matrix does not generate fluorescent light or phosphorescent light by an excitation light. The photoresist is disposed in the base matrix. The photoresist is fixed in a solid state through at least one method selected from the group consisting of thermal hardening, photo hardening, and drying. The colorant is disposed in the base matrix and includes light having a predetermined wavelength range. The wide-angle emission filter filters the excitation light regardless of an incident angle of the excitation light.
