FIELD: physics.
SUBSTANCE: matrix substrate includes a number of pixel elements, at least, one common electrode line, at least, one data line, at least, one first scan line and one second scan line parallel to the first scan line. The first scan line and the second scan line intersect with the data line. The pixel element includes the first pixel electrode, the second pixel electrode, the first transistor, the second transistor, the third transistor and a control circuit.
EFFECT: by adding one control circuit, the effect of colour change with a wide viewing angle is amplified and the image is frozen.
