    • An optical waveguide 30 having a bending groove 34 parallel to two long sides of a rectangular shape thereof. The optical waveguide 30 is bent along the bending groove 34 so as to come into close contact with a frame of an optical touch panel. This makes it possible to attach the optical waveguide 30 to the frame without misalignment during assembly. Therefore, the optical waveguide 30 can emit light beams in a direction perpendicular to one side of a rectangular display screen opposed to one long side of the rectangular shape thereof. Further, the width of the frame of the optical touch panel 30 can be made smaller than that of the optical waveguide 30. This makes it possible to achieve reduction in the width of the frame of the optical touch panel.
    • 具有平行于其长方形的两个长边的弯曲槽34的光波导30。 光波导30沿着弯曲槽34弯曲以与光学触摸面板的框架紧密接触。 这使得可以在组装期间将光波导30附接到框架而没有错位。 因此,光波导30可以在与矩形显示屏的与其长方形的一个长边相对的矩形显示屏的一侧的垂直方向上发射光束。 此外,可以使光学触摸面板30的框架的宽度小于光学波导30的宽度。这使得可以实现光学触摸面板的框架的宽度的减小。

    • A manufacturing method of an optical waveguide device which is capable of suppressing the surface roughening of core side surfaces of an optical waveguide when the optical waveguide is formed on a roughened surface of a substrate. An under cladding layer is formed on a roughened surface of a substrate made of a material that absorbs irradiation light, and then a photosensitive resin layer for the formation of cores is formed thereon. Irradiation light is directed toward this photosensitive resin layer to expose the photosensitive resin layer in a predetermined pattern to the irradiation light. When the irradiation light transmitted through the photosensitive resin layer for the formation of the cores and the under cladding layer reaches the surface of the substrate, the irradiation light is absorbed by the substrate, so that there is little irradiation light reflected from the surface of the substrate.
    • 一种光波导器件的制造方法,其在光波导形成在基板的粗糙面上时能够抑制光波导体的芯侧表面的粗糙化。 在由吸收照射光的材料制成的基板的粗糙化表面上形成下敷层,然后在其上形成用于形成芯的感光性树脂层。 照射光朝向该感光性树脂层,以相对照射光以规定的图案露出感光性树脂层。 当通过用于形成芯的感光性树脂层和下敷层的照射光到达基板的表面时,照射光被基板吸收,使得从该表面反射的照射光很少 基质。
