Mask, substrate with light reflective film, method for manufacturing light reflective film, liquid crystal display device, and electronic apparatus
View Patent ↗A substrate is provided with a light reflective film including a base and a reflective layer, in which a plurality of concave portions or convex portions formed on the surface of the base are randomly arranged in the plane direction in 100 to 2,000 RGB dot units or a whole screen unit, are formed using a mask in which light transmissive or non-transmissive portions are randomly arranged in the plane direction in 100 to 2,000 RGB dot units or the whole screen unit.
1. A mask for manufacturing a substrate with a light reflective film;
wherein light transmissive or non-transmissive portions are randomly arranged in a plane direction in 100 to 2,000 dot units or a whole screen unit;
wherein the light transmissive or non-transmissive portions are formed by forming a stripe-shaped random pattern in a row direction or in a column direction, and repeating the stripe-shaped random patterns in a plurality of lines.
2. The mask according to claim 1 ,
wherein the transmissive or non-transmissive portions in 100 to 2,000 dot units or a whole screen unit are formed by randomly arranging a prepared random pattern of light transmissive or non-transmissive portions for 3 to 12 RGB dots.
3. The mask according to claim 1 ,
wherein a diameter of the light transmissive or non-transmissive portions is any value within the range of 3 to 15 μm.
4. The mask according to claim 1 ,
wherein the light transmissive or non-transmissive portions have different diameters to form a plurality of kinds of light transmissive or non-transmissive portions.
