PROBLEM TO BE SOLVED: To provide an optical display device capable of switching in a state in which a design for luminous display and a design for display to be switched to are both distinctly displayed with small restrictions on both the designs.SOLUTION: An optical display device according to the present invention comprises: a first pattern layer P1 which does not transmit green light GL and transmits red light RL; a second pattern layer P2 which does not transmit the red light RL and transmits the green light GL; light emitting means 14 capable of emitting the green light GL or red light RL by switching; and a luminous layer V which is luminous more intensely with external light having a wavelength other than wavelengths of the green light GL and red light RL than with the green light GL and red light RL.SELECTED DRAWING: Figure 2 |
