A light-absorbing, neutral density filter for an electronic device display. More specifically, a light-absorbing, neutral density filter applied as a shield, protective film, or protective coating layer for an electronic device display that blocks ultraviolet light, high energy visible light, and at least a portion of blue light. The neutral density filter comprises a polymer substrate and an absorbing agent. L'invention concerne un filtre de densité neutre, absorbant la lumière pour un élément d'affichage de dispositif électronique. L'invention concerne plus particulièrement un filtre de densité neutre, absorbant la lumière appliqué en tant qu'élément de protection, film de protection, ou couche de revêtement de protection pour un élément d'affichage de dispositif électronique, qui bloque la lumière ultraviolette, la lumière visible haute énergie, et au moins une partie de la lumière bleue. Le filtre de densité neutre comprend un substrat polymère et un agent absorbant.
