The present invention relates to a master mold for a smart window, a manufacturing method for the same, and a film for a smart window thereby. The master mold for a smart window has multiple groove patterns. The master mold for a smart window includes: a base pattern part with groove patterns in certain direction; and multiple adjacent pattern parts that are accordingly adjacent to the groove pattern and have distinctive but even groove patterns. The master mold for a smart window is formed while the direction of polarization of groove patterns is gradually rotated in a fixed angle on the basis of the direction of polarization of the groove patterns in the base pattern part. Accordingly, the transmittance of the film for a smart window can be controlled according to the degree of overlap of the film for smart window, and the transmittance can be very gradually changed. |
