Abstract: A polarizing member includes a base layer, a first reflection preventing layer and a second reflection preventing layer. A base layer polarizes light, generating polarized light. A first reflection preventing layer is disposed on the base layer, diffusing the polarized light and generating first diffused light. A second reflection is disposed on the first reflection preventing layer, diffusing the first diffused light and generating second diffused light.
