摘要： An image display apparatus (100), which has a high contrast and can suppress the contrast variation and the effect of unwanted reflections regardless of the environment, comprises a luminescent layer (104); an excitation source (103) which excites the luminescent layer; a front layer (101) which obtains display light by transmitting light generated by the luminescent layer excited by the excitation source; and a periodic structure (105) which is provided between the front layer and the luminescent layer and has a periodic refractive index distribution in a surface parallel to the front layer, wherein the periodic structure satisfies a relation of a following expression and the periodic interval of the periodic structure is 1 µm or greater and 3 µm or less.
1 N sub ≤ N eff
Where N eff denotes an effective refractive index of the periodic structure and N sub denotes a refractive index of a medium constituting the front layer.摘要翻译： 一种图像显示装置（100），其具有高对比度并且可以抑制对比度变化以及不受环境影响的不希望的反射，所述图像显示装置（100）包括发光层（104）; 激发发光层的激发源（103） 前层（101），其通过透射由激发源激发的发光层产生的光来获得显示光; 以及周期结构（105），设置在所述前层和所述发光层之间，并且在与所述前层平行的表面中具有周期性折射率分布，其中，所述周期结构满足以下表达式和 周期结构为1μm以上且3μm以下。 1
