Patent ID: 7630115

Claim:
An electro-optical device comprising: a first substrate; a second substrate; a liquid crystal layer disposed between the first and second substrates; a display dot including therein a transmission portion and a reflection portion; a reflection layer disposed between the first substrate and the liquid crystal layer, the reflection layer including the reflection portion of the display dot; an underlayer disposed between the liquid crystal layer and the reflection layer, the underlayer including a main portion corresponding to the reflection portion of the display dot and a relatively thin portion corresponding to the transmission portion of the display dot so that the liquid crystal layer has a greater thickness at the transmission portion than at the reflection portion; and a protection layer disposed between the liquid crystal layer and second substrate, the protection layer including a main portion corresponding to the reflection portion of the display dot and a relatively thin portion corresponding to the transmission portion of the display dot so that the liquid crystal layer has a greater thickness at the transmission portion than at the reflection portion.
