    • An image display apparatus includes: an image display section that displays a two-dimensional image; and a variable lens array that includes a first substrate having a first electrode, a second substrate having a second electrode, and a liquid crystal layer which is disposed between the first substrate and the second substrate. The value of the refractive power of each lens line thereof is changed by a voltage which is applied between the first electrode and the second electrode. The variable lens array is disposed to be opposed to the image display section. Wall-shaped or columnar spacers are provided in a place, in which an orientation direction of liquid crystal molecules of the liquid crystal layer is unchanged when the value of the refractive power of each lens line thereof is changed, between the first substrate and the second substrate of the variable lens array.
    • 图像显示装置包括:显示二维图像的图像显示部; 以及可变透镜阵列,其包括具有第一电极的第一基板,具有第二电极的第二基板和设置在所述第一基板和所述第二基板之间的液晶层。 其每个透镜线的折射力的值通过施加在第一电极和第二电极之间的电压而改变。 可变透镜阵列设置成与图像显示部分相对。 在第一基板和第二基板之间的液晶层的液晶分子的取向方向在各透镜线的折射力变化的值不变的地方设置有壁状或柱状的间隔物, 可变透镜阵列的基板。
