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: Disclosed is an optical waveguide element wherein a plurality of Mach-Zehnder waveguides to be used for DQPSK modulation and the like are integrated on a thin substrate and the on/off extinction ratio is improved. The optical waveguide element has the thin board, which is formed of a material having electrooptical effects and has a thickness of 20 μm or less, and an optical waveguide formed on the front surface or the rear surface of the thin board. The optical waveguide has the plurality of Mach-Zehnder waveguide sections, and multiplexes optical waves outputted from two or more Mach-Zehnder waveguide sections. In the multiplexing section in each Mach-Zehnder waveguide section (MZA), a triply branched waveguide, which is composed of a waveguide for output (c1) and two waveguides for radiation (b1, b2) disposed to sandwich the waveguide for output, is formed. High-order mode light absorption regions (d1, d2) are formed between the waveguide for output and the waveguides for radiation in the triply branched waveguide.
