A typical liquid crystal lens includes liquid crystal sandwiched between transparent substrates, which are patterned with ring electrodes. Applying a voltage across the electrodes causes the liquid crystal molecules to rotate, changing their apparent refractive index and the lens's focal length. The ring electrodes are separated by gaps and get narrower toward the lens's periphery. If the ring electrodes are too narrower, their cannot switch the liquid crystal well. To address this problem, an inventive liquid crystal lens includes a substrate with a stepped surface that defines concentric liquid crystal regions with thicknesses that increase with lens radius. Each region is switched by a different set of ring electrodes, which may be on, under, or opposite the stepped surface. Within each region, the ring electrodes get narrower farther from the lens's center. But the ring electrodes' widths also increase with liquid crystal thickness, offsetting the decrease in width that degrades lens performance.

In an electro-optical device, a relay electrode (first electrode) includes a conduction section that overlaps the projection portion of an inter-layer insulation film, and the conduction section is exposed from the surface (flat surface) of the inter-layer insulation film. An insulation film which has a film thickness thinner than the height of the projection portion is formed on the surface (flat surface) of the inter-layer insulation film, and a pixel electrode is electrically conducted to the conduction section through the opening of the insulation film. In this case, since the opening is shallow, a large uneven part is hardly generated on the surface of the pixel electrode.
