PURPOSE: To propose the specific two-dimensional arrangement of a hologram array or microlens array constituting color filters formed by using holograms and to improve the utilization efficiency of a back light. CONSTITUTION: The arrangement of the microholograms or microlenses Aij of the case (striped type) the coloring cells or liquid crystal cells R, G, B corresponding thereto of a liquid crystal color display device are arranged in alignment in respective colunms is such that the microholograms or microlenses Aij exist in the same positions even if the column number (i) varies. Namely, the respective microholograms or microlenses Aij are arranged in aligmnent in both longitudinal and transverse directions. The microholograms or microlenses Aij of the adjacent columns are arranged with a delay by a 1/3 period in the case of a mosaic type and with a delay by a 1/2 period in the case of a triangle type. |
