Abstract
A color filter and a manufacturing method thereof, and a display device are provided. The color filter includes a color filter substrate, a plurality of sub-pixel regions, wherein each of the sub-pixel regions includes a first signal region, a second signal region, and a laser path disposed between the first signal region and the second signal region, a first light-shielding sheet disposed on the first signal region and covered with a first indium tin oxide layer, and a second light-shielding sheet disposed on the second signal region and covered with a second indium tin oxide layer. Wherein, the first signal region receives signals through the first indium tin oxide layer, and the second signal region receives signals through the second indium tin oxide layer, therefore improving the problem of signal transmission delay caused by the regional signal impedance difference of the indium tin oxide layer.
