Abstract
A color filter, a preparation method therefore, an array substrate and a display device are provided. The color filter includes a plurality of filter units (20) provided on a base substrate (10) for transmitting light of different colors, and a light shielding layer (30) located between adjacent filter units (20) for transmitting light of different colors. The filter unit (20) includes a first surface facing the base substrate (10), a second surface facing away from the base substrate, and a third surface connecting the first surface and the second surface. The light shielding layer (30) is provided on the third surface of at least one of two adjacent filter units (20) transmitting light of different colors.
