Abstract: A virtual image display apparatus includes an organic EL device that outputs light having one kind of wavelength band, a light guide member, and a reflection-type volume hologram that is disposed on a first face of the light guide member and diffracts and reflects light of a predetermined wavelength band of the light that has entered. The organic EL device includes an optical resonance structure that causes the above-mentioned light of one-kind wavelength band to resonate.
