Display apparatus

A display apparatus comprising:

• a liquid crystal element having a liquid crystal layer sealed in a space between a first substrate and a second substrate that are arranged face to face with each other, liquid crystal molecules being aligned in a predetermined alignment state in the liquid crystal layer, the liquid crystal element being provided with a plurality of pixels that change the alignment state of the liquid crystal molecules in response to the application of a voltage to the liquid crystal layer to control the transmission of a light;
• a protective plate that is greater in area than the first substrate and that is disposed so that the first substrate intervenes between the protective plate and the second substrate;
• a first polarizing plate that has an absorption axis in a predetermined direction and that is disposed between the protective plate and the first substrate to be in close contact with the protective plate;
• a first quarter-wavelength retardation plate that has a slow axis in a direction intersecting with the absorption axis of the first polarizing plate at an angle of 45° and that is disposed between the first substrate and the first polarizing plate to be in close contact with the first substrate;
• and
• a second quarter-wavelength retardation plate that has a slow axis in a direction perpendicular to the slow axis of the first quarter-wavelength retardation plate and that is disposed between the first polarizing plate and the first quarter-wavelength retardation plate to be in close contact with the first polarizing plate.
