摘要： An optical disc apparatus has the following arrangements. Specifically, the optical disc apparatus includes a lock pin and a lock arm. The lock pin is disposed on a side of an inner surface of a case of the apparatus, being tapered in a protruding direction thereof. The lock arm is disposed on a side of a tray of the apparatus. The lock arm, urged by a resilient member, includes a hook portion to be engaged with an inclined surface of the lock pin. When the tray has moved to a predetermined position within the case, the lock arm is engaged with the lock pin, so that the tray is held in position at the predetermined position. When an impact force equal to, or more than, a predetermined value is applied to the optical disc apparatus, the hook portion of the lock arm is displaced in the protruding direction of the lock pin along the inclined surface of the lock pin, thereby disengaged from the lock pin. Engagement of the tray is thereby released.

摘要： A front surface of the opposite electrode of a liquid crystal display panel is formed in a curved shape. The relation between the reflecting surface of the pixel electrode and the curved surface of the opposite substrate is defined so that a leaving direction of the light that is reflected by the first face of the opposite substrate is different from a leaving direction of light that is emitted from the first face of the opposite substrate after having been reflected by the pixel electrodes through the liquid crystal layer. Thus, undesired light on the front surface of the opposite substrate is separated from light that is displayed. Consequently, an image free of dazzling and deterioration of contrast ratio due to undesired reflected light can be obtained with a high contrast ratio. In a display apparatus containing the reflection type liquid crystal display, an incident surface to a dichroic prism is an inclined surface including a curved surface, not a surface that is perpendicular to the optical axis. Thus, signal light that is reflected on each reflection type liquid crystal display panel and that is displayed can be separated from undesired light that is reflected on the surface of the dichroic prism. Thus, an image with a high quality, and a high contrast ratio can be displayed.

摘要翻译： 液晶显示面板的相对电极的前表面形成为弯曲形状。 限定像素电极的反射面与相对基板的曲面之间的关系，使得由相对基板的第一面反射的光的离开方向与发出的光的离开方向不同 在由像素电极经过液晶层反射之后，从相对基板的第一面开始。 因此，相对基板的前表面上的不期望的光与显示的光分离。 因此，可以以高对比度获得由于不希望的反射光引起的无眩光和对比度的劣化的图像。 在包含反射型液晶显示器的显示装置中，分色棱镜的入射面是包括弯曲表面而不是垂直于光轴的表面的倾斜表面。 因此，在每个反射型液晶显示面板上反射并被显示的信号光可以与在二向色棱镜的表面上反射的不期望的光分离。 因此，可以显示具有高质量和高对比度的图像。
