Abstract:
In order to provide a projection lens barrel and a projection display device that are capable of correcting the optical characteristics of a plurality of lens groups, a projection lens barrel, comprising a lens optical system causing light from an image display element to be formed as a projected image on a screen, also comprises correction mechanisms that move each of at least two lens groups along an optical axis and correct the optical characteristics to be corrected, said lens groups each having different optical characteristics for correction in order to suppress reduction in image quality of a projected image caused by changes in optical characteristics caused by temperature changes in the projection lens barrel.

Claim (Index 16):
The projection lens barrel according to  claim 9 , wherein of the correction mechanisms, at least the one correction mechanism is provided on a lens group that is disposed on a location which is a screen side with respect to a lens group adjacent to a stop of the projection lens barrel on the screen side, and at a location which is outside of a casing of a projection display device to which the projection lens barrel is attached.
