Patent ID: 8748213

Claim:
A method to form a light transmission member comprising: a series of processes to form light transmission portions, each of the processes including forming a light transmission film and leaving the light transmission film in any of a plurality of sections of a predetermined plane, and each of the processes being performed for each formation of each light transmission film having different light transmission properties, the plurality of sections of the predetermined plane including a first section, a second section, a third section, a fourth section, a fifth section, a sixth section, a seventh section, an eighth section, and a ninth section, regarding a first direction of the predetermined plane, the first section is between the second section and the third section, the second section and the third section are between the sixth and the seventh section, the second section is adjacent to the first section and sixth section, and the third section is adjacent to the first section and the seventh section, regarding a second direction that intersects the first direction of the predetermined plane, the first section is between the fourth section and the fifth section, the fourth section and the fifth section are between the eighth section and the ninth section, the fourth section is adjacent to the first section and the eighth section, and the fifth section is adjacent to the first section and the ninth section, wherein the light transmission portion disposed in the first section exhibits a green color, red color and blue color light transmittance at or above a predetermined value, the light transmission portions disposed in each of the second section, the third section, the fourth section, and the fifth section exhibit at least one of a green color, red color and blue color light transmittance at or above a predetermined value, and the light transmission portions disposed in each of the second section, the third section, the fourth section, and the fifth section exhibit at least one of a green color, red color and blue color light transmittance below the predetermined value, and wherein, in the series of processes, after the light transmission portions are formed for the second section, the third section, the fourth section, and the fifth section, the light transmission portions are formed for the first section, the sixth section, the seventh section, the eighth section, and the ninth section.
