A projection-type display apparatus synthesizes and emits light emitted from a plurality of liquid crystal devices with a projection optical system. Provided that a liquid crystal at an inner side of a seal material in the plurality of liquid crystal devices is V1 in volume and a liquid crystal in a display region is V2 in volume in the plurality of liquid crystal devices, in a second liquid crystal device (a liquid crystal device for blue light) on which light having a wavelength shorter than the wavelength of light being incident on a first liquid crystal device (a liquid crystal device for green light) is incident on the display region, a liquid crystal volume ratio V1/V2 is greater than that of the first liquid crystal device, among the plurality of liquid crystal devices.
