Abstract: PURPOSE: To relieve the influence of a filter material, and enhance contrast by controlling an external light reflecting quantity of filters by controlling the area of hole parts. CONSTITUTION: A black matrix 20 of a black pigment particle is formed on an inside surface of a face plate 10 of a transparent base board, and blue, green and red filters 30, 40 and 50 are formed in these hole parts. Blue, green and red color phosphor layers 34, 44 and 54 are formed on these filters in response to the hole parts. In respective visibility of blue, green and red color light emitting phosphors, since green is the largest, a hole part 22G in which the green filter 40 and the green color light emitting phosphor layer 44 are formed is made smaller by 10% in its area than hole parts 22B and 22R in which the blue and red filters and the phosphor layers are formed. In this way, since a quantity reflected by the external light is reduced by controlling the area, a contrast characteristic can be improved more than when the areas of the hole parts 22G, B and R are equal to each other.
