Abstract: Provided are a laminated glass which has a reduced occurrence of voids and accumulation of liquid crystal, and a production method for the laminated glass. Also provided is a laminated glass which can prevent deterioration of a sealing material. This laminated glass 1 comprises a first glass plate 33A, a first intermediate film 31A, a liquid crystal film 10, a second intermediate film 31B, and a second glass plate, which are layered and disposed in this order, wherein the first glass plate 33A and the second glass plate 33B have a larger outer shape than that of the liquid crystal film 10, and a spacer 32 is provided in at least a portion of a region which is interposed between the first glass plate 33A and the second glass plate 33B and in which the liquid crystal film 10 is not disposed.

Abstract: Provided is an optical film that can suppress rainbow unevenness when viewed with the naked eyes without increasing the in-plane phase difference. The optical film has a low-refractive index layer on a plastic film, the plastic film is a biaxially stretched plastic film with an in-plane phase difference of 2500 nm or less, the low-refractive index layer is located on the outermost surface, and the optical film has a region in which ΔEab satisfies specific conditions, wherein the ΔEab is calculated from the differences between the L* value, the a* value, and the b* value obtained by measuring a laminate 1 including the optical film, the polarizer, and the surface light source under specific conditions and the L* value, the a* value, and the b* value obtained by measuring a laminate 2 including the polarizer and the surface light source under specific conditions, respectively.
