Abstract
An external light blocking film includes a base of transparent resin and an external light blocking pattern having a plurality of external light blocking parts. The external light blocking part is formed by filling a groove with a light absorption material. One end of the external light blocking part is exposed on a surface of the base, and the other end of the external light blocking part is buried in the base. The one end has a shape of a stripe and the other end has a shape of a zigzag curve when viewed from the front. Furthermore, a method of fabricating an external light blocking film and a filter for a display device having an external light blocking film are provided. The external light blocking film has an excellent ability to absorb external light. A complicated pattern of the external light blocking film can be easily formed without additional machining processes, whereby the fabrication time and cost can be saved.
