Thin film transistor array panel and liquid crystal display

A liquid crystal display, comprising:

• a first substrate;
• a gate insulating layer formed on the first substrate;
• a lower passivation layer formed on the gate insulating layer;
• an upper passivation layer formed on the lower passivation layer and comprising an organic insulating material;
• a pixel electrode formed on the upper passivation layer;
• a second substrate facing the first substrate;
• and
• a liquid crystal layer formed between the first substrate and the second substrate,
• wherein the gate insulating layer, the lower passivation layer, and the pixel electrode satisfy the following condition equations:
• 4(dGnG+dPnP)=, which is an even multiple of the wavelength, and
• 4dInI=, which is an even multiple of the wavelength, and
• wherein the thicknesses of the gate insulating layer, the lower passivation layer, and the pixel electrode are represented as dG, dP, and dI, respectively, and the refraction index of the gate insulating layer, the passivation layer, and the pixel electrode are represented as nG, nP, and nI, respectively.
