In a liquid crystal display device having a front window, light from a backlight is prevented from leaking through chamfered edges of the front window. An upper polarizing plate is formed on an opposing substrate and a light shielding material is formed abutting on an outer edge of the upper polarizing plate. Edges of the upper polarizing plate are located inward of edges of the front window. The upper polarizing plate and the front window are bonded with a boding material including an ultraviolet curable resin. The ultraviolet curable resin also lies over the light shielding material. Chamfers are formed in the front window and the ultraviolet curable resin does not adhere to the chamfers of the front window. By this structure, light from the backlight is prevented from entering the internal part of the front window through the chamfers of the front window and light leakage is prevented.
