发明名称 Liquid crystal display device
摘要 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.

主权项 1. A liquid crystal display device having a liquid crystal panel, comprising: a TFT substrate on which pixel electrodes and TFTs for controlling signals for the pixel electrodes are arranged in a matrix; a counter substrate on which color filters corresponding to the pixel electrodes and a black matrix are formed on an opposing side to the TFT substrate; and a backlight disposed at the back side of the liquid crystal display panel; wherein an upper polarizing plate and a light shielding member are in direct contact with the counter substrate, the light shielding member being disposed at a portion outside the upper polarizing plate; a front window is bonded onto the upper polarizing plate with a UV-ray curable resin; the UV-ray curable resin is disposed over the upper polarizing plate and the light shielding member, and a light shielding tape is disposed over the UV-ray curable resin; in plan view, the UV-curable resin completely covers the upper polarizing plate; in plan view, the UV-curable resin exists between the front window and the upper polarizing plate, and surrounds an outer edge of the front window; in plan view, the light shielding member is formed under a periphery of the upper polarizing plate, the light shielding member surrounds an outer edge of the upper polarizing plate, and the light shielding member surrounds the outer edge of the front window; and in plan view, the light shielding tape overlays on the UV-curable resin, and, in plan view, the light shielding tape surrounds the outer edge of the front window.
