1. A window for preventing a whitening event, the window comprising:
a base layer; and
a hard coating layer on the base layer, the hard coating layer including:
a first layer on the base layer, the first layer having a first thickness; and
a second layer on the first layer, the second layer including an antistatic agent and having a second thickness,
wherein the hard coating layer has a hardness reduction rate expressed by Equation 1 below,

OG Complex Work Unit Math
wherein, H is a hardness reduction rate (%) of the hard coating layer, D1 is a hardness measured from the hard coating layer at a temperature of 60 degrees Celsius with a relative humidity of 93 percent, and D2 is a hardness measured from the hard coating layer at a room temperature with a relative humidity of 30 percent, and
the hardness reduction rate H of the hard coating layer is configurated to have a value of 50 percent or less.
