Display with black matrix

A display, comprising:

• a first substrate;
• a plurality of gate lines and a plurality of data lines disposed on the first substrate and crossing with each other to define at least one first color pixel area, at least one second color pixel area, and at least one third color pixel area;
• a first color pixel transistor, a second color pixel transistor, and a third color pixel transistor respectively located in the first color pixel area, the second color pixel area, and the third color pixel area, and electrically connected to the corresponding gate lines and the corresponding data lines, wherein the first color pixel transistor comprises a first color pixel active layer, the second color pixel transistor comprises a second color pixel active layer, and the third color pixel transistor comprises a third color pixel active layer;
• a second substrate disposed on the first substrate;
• and
• a black matrix disposed between the first substrate and the second substrate and corresponding to the gate lines and the data lines,
• wherein the black matrix has a first portion covering the first color pixel transistor and a second portion covering the third color pixel transistor, and the first portion extends a first shading distance from an edge of the first color pixel active layer in a direction perpendicular to the gate lines, the second portion extends a second shading distance from an edge of the third color pixel active layer in the direction, wherein the second shading distance is larger than the first shading distance, and the first color has a wavelength longer than that of the third color.
