Abstract
In a liquid crystal display having liquid crystal sealed between first and second substrates opposing one another, the first substrate is provided with data lines (56) formed overlapping pixel electrodes (58). By forming color filters (1) in a layer between the data lines (56) and the pixel electrodes (58), the distance between the data lines (56) and the pixel electrodes (58) is increased, reducing parasitic capacitance generated therebetween. Effective voltage application to the pixel electrodes (58) is thereby accomplished, allowing increase in contrast. No decrease in transmittance is caused because the thickness of the planarizing film (2) is not increased.
