PROBLEM TO BE SOLVED: To lessen the black floating of many light emitting elements and to improve the contrast of a screen front pair by forming the shades of light in the peripheral parts of the many light emitting elements by light shade forming means disposed in the peripheral parts of the many light emitting elements. SOLUTION: The light shade forming means 16 are integrally formed in the peripheral parts 15 of the individual light emitting diodes(LEDs) 3 in order to individually form the shades of the light between many lowers 14 on the front surface of a front surface cover 12. The light shade forming means 16 are formed of microlouvers 17 which are smaller than louvers 14, have a horizontal shape formed in sectionals shape to a nearly saw tooth shape and are formed of fine rugged surfaces of plural upper and lower stages. Then, the external light SL 1, such as direct sunshine, made incident diagonal from above is regulated by the louvers 14 which are eaves of a large size, by which the shades 18 of light may be formed on the front surface and upper part of these LEDs 3. |
