    Abstract: A molded contact lens comprising a stiffer optic zone relative to the peripheral zone of the contact lens provides an optical element for correcting astigmatism without the need for or substantially minimizing the need for the correction of rotational misalignment. The higher elastic modulus optic zone vaults over the cornea thereby allowing a tear lens to form. The tear lens follows or assumes the shape of the back surface of the contact lens. The combination of the tear lens and the optical zone provide an optical element for correction of refractive error.

The inter-layer insulation film needs to be thick and thus an inter-layer insulation film needs to be thin. A first capacitance line is formed on a surface of the inter-layer insulation film on the side of a pixel electrode. Thus, the first capacitance line shields a section between a gate electrode and the second capacitance electrode to which a drain potential is applied.
