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.
Abstract translation: 可以防止由背光发出的光通过液晶显示装置的前窗的倒角部分泄漏。 上偏振片接合在对置基板上，前窗用紫外线固化树脂粘合剂粘合在上偏振片上。 前窗被倒角，并且在倒角部分上形成遮光构件。 紫外线粘合剂存在于倒角部和上偏振片或相对基板的表面之间，偏振片的外端存在于比前窗的外端外侧的位置。 由于形成了用于倒角部分的遮光构件，所以来自背光源的光不会从倒角部分穿透。 因此，即使视角较大，也可以防止屏幕周边的光泄漏。

Abstract: A single light guide plate illuminates both first and second liquid crystal display panels opposed to each other, the second liquid crystal display panel having a larger display area than that of the first liquid crystal display panel. A light-absorbing sheet is provided between the light guide plate and the first liquid crystal display panel to absorb light from the light guide plate and has a light-transmitting part aligned with the first liquid crystal display panel in a direction from the light guide plate toward the first liquid crystal display panel to transmit light from the light guide plate to the first liquid crystal display panel. A reflective polarizing sheet is provided between the second liquid crystal display panel and the light guide plate. The light-absorbing sheet eliminates brightness unevenness on the second liquid crystal display panel, which would otherwise occur due to the influence of the first liquid crystal display panel, and the reflective polarizing sheet allows effective utilization of light from the light guide plate.
