| 摘要 |
The invention provides an electrooptical device, such as a liquid-crystal device that presents a high-contrast, bright and high-quality image, by reducing a malfunction due to a transverse electric field in an electrooptical material, such as a liquid crystal. The electrooptical device includes pixel electrodes on a TFT array substrate and a counter electrode on a counter substrate. Arranged beneath the pixel electrodes in the TFT array substrate are protrusions in an area facing a spacing between adjacent pixel electrodes. The method for manufacturing such an electrooptical device includes: forming a pattern including a wiring, a TFT, etc. on the TFT array substrate; planarizing the surface of a laminate of the substrate including the pattern; and forming the protrusion by subjecting the planarized surface to photolithographic and etching processes.
