Provided is a virtual image display device including an imaging light emitting device, a light-guiding member configured to guide imaging light emitted from the imaging light emitting device, and an emission-side diffraction element provided at a light-emitting portion of the light-guiding member and configured to emit the imaging light by diffraction. In the emission-side diffraction element, a light amount difference between a first component light and a second component light of the imaging light, the first component light being emitted as a central image at a first angle φ of 0° and the second component light being emitted as a peripheral image at a second angle φ of ±θ (θ>0°), is equal to or less than 20%.
