Summary:PROBLEM TO BE SOLVED: To provide an image display device and head-mounted display which facilitate routing of an optical fiber and can reduce intensity of light that has entered the optical fiber from a light source unit to no more than a predetermined level.SOLUTION: An image display device 1 includes a light source unit for emitting light, a first optical fiber 7 which receives the light emitted by the light source unit, and a second optical fiber 8 which has a smaller core diameter than the first optical fiber 7 and receives a portion of the light emitted from the first optical fiber 7. 【課題】光ファイバーの引き回しを容易なものとするとともに、光源部から光ファイバーに入射した光の強度を所定値以下に低下させることができる画像表示装置およびヘッドマウントディスプレイを提供すること。【解決手段】画像表示装置１は、光を出射する光源部と、光源部から出射された光が入射する第１光ファイバー７と、第１光ファイバー７よりもコア径が小さく、かつ、第１光ファイバー７から出射された光の一部が入射する第２光ファイバー８と、を備える。【選択図】図２
