Abstract: A window includes a base layer and a hard coating layer on the base layer. The hard coating layer includes a first layer on the base layer and of a first thickness, and a second layer on the first layer and of a second thickness. The second layer includes an antistatic agent. The hard coating layer has a hardness reduction rate of 50 percent (%) or less expressed as follows.

In the equation above, H is a hardness reduction rate (%) of a target layer, D1 is a hardness reduction rate measured from the target layer at a temperature of 60 degrees Celsius (° C.) with a relative humidity of 93%, and D2 is a hardness reduction rate measured from the target layer at a room temperature with a relative humidity of 30%.
