Abstract: Light emitted by a backlight can be prevented from leaking through a chamfered portion of a front window of a liquid crystal display device. An upper polarizing plate is bonded over the counter substrate, and a front window is bonded over the upper polarizing plate with a UV-curable resin adhesive. The front window is chamfered and a light shielding member is formed on the chamfered portion. The UV adhesive exists between the chamfered portion and the surface of the upper polarizing plate or the counter substrate, and an outer end of the polarizing plate exists at a point outer than an outer end of the front window. Since the light shielding member for the chamfered portion is formed, light from the backlight does not penetrate from the chamfered portion. Thus, light leakage at a periphery of a screen can be prevented even when the view angle is large.
