  According to the light emitting unit 60 described above, the light of the light source 11 incident from one end surface 64a of the light guide plate 64, for example, representing a part of the outline of the capital letter “J” of the alphabet is provided to face the one end surface 64a. The light is emitted from the other end surface 64b. The light of the light source 11 incident from one end surface 65a of the auxiliary light guide plate 65 is emitted from the other end surface 65b provided to face the one end surface 65a. . Further, the light of the light source 11 incident from the one end surface 65 a of the auxiliary light guide plate 65 is transmitted from the auxiliary light guide plate 65 and then emitted from the contact surface 65 s that contacts the one main surface 64 c of the light guide plate 64. Then, the light is emitted to the outside through the other main surface 65e facing the one main surface 64c of the light guide plate 64. Similarly, the light of the light source 11 incident from the one end surface 65a of the auxiliary light guide plate 65 propagates through the auxiliary light guide plate 65, and then exits from the surface in contact with the one main surface 63c of the light guide plate 63. The light is output to the outside through the other main surface 63e facing the one main surface 63c of the light guide plate 63.

  Further, for example, the light of the light source 11 incident from one end surface 64 a of the light guide plate 64 is emitted from the entire other main surface 64 e of the light guide plate 64.

Therefore, it becomes easier to visually recognize the “J” as compared to the case where light is led out only from one end face of the light guide plates 61 to 64 that represents the outline of “J”.

  Further, according to the display device according to the fourth embodiment of the present invention, the emission wavelength of the light source 11 incident from one end surface 64a of the light guide plate 64, for example, representing a part of the outline of the capital letter “J” of the alphabet, When the light emission wavelength of the light source 11 incident from one end surface 65a of the auxiliary light guide plate 65 is the same, for example, the inside of the capital letter "J" of the alphabet is shown in a striped pattern, the other main surface 64e of the light guide plate 64 Since the entire light is emitted substantially uniformly with light of a predetermined wavelength, the other main surface 64e of the light guide plate 64 facing the contact surface 65s of the auxiliary light guide plate 65 also emits light. Monochromatic light having light intensity in a striped pattern is derived from the above.

  Furthermore, according to the display device according to the fourth embodiment of the present invention, the light emission wavelength of the light source 11 incident from one end surface 64a of the light guide plate 64, for example, representing a part of the outline of the capital letter “J” of the alphabet, When the light emission wavelength of the light source 11 incident from one end surface 65a of the auxiliary light guide plate 65 is different, for example, the inside of the capital letter “J” is shown in a striped pattern, the entire other main surface 64e of the light guide plate 64 Are emitted substantially uniformly with light of a predetermined wavelength, and light is emitted with light of different wavelengths on the other main surface 64e of the light guide plate 64 facing the contact surface 65s of the auxiliary light guide plate 65. Therefore, in such a case, light of different wavelengths is emitted in a striped pattern from the other main surface 64e of the light guide plate 64.

  Further, according to the display device according to the fourth embodiment of the present invention, the auxiliary light guide plates 65 to 67 are joined inside the region surrounded by the light guide plates 61 to 64 in parallel with a predetermined interval.
