20120162742 | ELECTRO-OPTICAL DEVICE AND ELECTRONIC APPARATUS - An electro-optical device includes an electro-optical material, a first lens which is arranged at an incident side of the light and is provided so as to correspond to a pixel, and a condenser lens which is arranged at an emitting side of the light and is provided so as to correspond to the pixel. Condensation degrees of the first lens are larger than that of the second lens, and distances between the first lens and the electro-optical material are smaller than distances between the second lens and the electro-optical material. | 06-28-2012 |
20120242915 | LIQUID CRYSTAL DEVICE AND PROJECTOR - In a liquid crystal device, a liquid crystal layer is interposed between first and second substrates. The liquid crystal device includes a light-shielding layer formed in a lattice shape and a condensing lens condensing light incident on the side of the first substrate into the inside of an opening portion of a light-shielding section. In the second substrate, a prism element condensing the light which has been incident from the side of the first substrate and has passed and spread through the condensing lens, the liquid crystal layer, and the opening portion is disposed at a position overlapping the light-shielding layer in a plan view. The prism element includes a groove formed in the second substrate. | 09-27-2012 |
