发明名称 ELECTRO-OPTICAL APPARATUS AND PROJECTOR
摘要 <P>PROBLEM TO BE SOLVED: To provide an electro-optical apparatus and a projector improving light use efficiency. <P>SOLUTION: The width T1 of a groove 40 is preferably the range of T3&le;T1&le;T3+2t. The width T1 of the groove 40 of the prism element 30 of the invention is T1&ge;T3+2t, which is within the range (the maximum of the range). Accordingly, light transmitted through the pixel area of a counter substrate 2 can be made incident on a projection lens 114 to the maximum without being substantially absorbed by light shielding parts 23 and 33. This improves light use efficiency. <P>COPYRIGHT: (C)2008,JPO&INPIT
