    • An image forming device includes a display panel for exposing a photosensitive recording medium to light. The display panel includes a light transmissive substrate, and a plurality of light emitting elements provided on the substrate. The substrate includes a first surface for facing the photosensitive recording medium, a second surface which is opposite from the first surface, and thickness T defined as spacing distance between the first surface and the second surface. The plurality of light emitting elements is provided on the second surface to be spaced from each other. When refractive index of the substrate is expressed by n and minimum spacing distance between the plurality of light emitting elements is expressed by S, the thickness T satisfies the following inequality: T ≤ S ⁢ n 2 - 1 2 .
    • 图像形成装置包括用于将光敏记录介质曝光的显示面板。 显示面板包括透光基板和设置在基板上的多个发光元件。 基板包括面对感光记录介质的第一表面,与第一表面相对的第二表面和被定义为第一表面和第二表面之间的间隔距离的厚度T. 多个发光元件设置在第二表面上以彼此间隔开。 当衬底的折射率由n表示并且多个发光元件之间的最小间隔距离由S表示时,厚度T满足以下不等式: T <= n 2 - 1 / mrow> 2
