Patent ID: 7660022

Claim:
An electro-optical device comprising: an electro-optical panel which has a plurality of electro-optical elements whose light-emitting characteristics or transmissive characteristics are changed by electrical energy applied; and a converging lens array which has a plurality of distributed index lenses, each transmitting light traveling from the electro-optical panel to form an erect image with respect to an image on the electro-optical panel, the images formed by the plurality of distributed index lenses constituting a continuous image; wherein the electro-optical panel is directly bonded to the converging lens array; and wherein, when the refractive index of each transmissive element provided between electro-optical elements of the electro-optical panel and the converging lens array is n i , the thickness of each transmissive element is d i , the number of transmissive elements is m, and an object distance of the converging lens array to the electro-optical panel in the air is Lo, the following expression 1is satisfied: [ Expression ⁢ ⁢ 1 ] 0.9 × ∑ i = 1 m ⁢ d i n i ≤ L o ≤ 1.1 × ∑ i = 1 m ⁢ d i n i .
