THREE-DIMENSIONAL DISPLAY DEVICE

A three-dimensional display device includes a display panel and a plurality of elongate optical elements overlying the display panel. The display panel includes a plurality of subpixels arranged in rows and columns. At least one of the subpixels has a subpixel width along a row direction of the rows of the subpixel. At least one of the elongate optical elements is slanted at a slant angle to a column direction of the subpixel columns and has a pitch along the row direction, wherein the slant angle is 20 to 30 degrees. 种三维显示设备包括显示面板、及覆盖于该显示面板的多个条状光学组件。该显示面板包括由多行和多列排列而成的多个子像素，至少子像素沿着该多个子像素行的行(row)方向具有子像素宽度；至少条状光学组件相对于该多个子像素列的列(column)方向以倾斜角倾斜，并沿着该行方向具有间距；其中，该倾斜角为20至30度。
