Abstract: An electrooptical device of a projection display device includes a first driving element and a second driving element. The first driving element switches a position of a first mirror between a first turn-on position, in which the first mirror reflects a first light-source light beam from a first irradiation direction in an ON-direction, and a first turn-off position, in which the first mirror reflects the first light-source light beam in a first OFF-direction. The second driving element switches a position of a second mirror between a second turn-on position, in which the second mirror reflects a second light-source light beam in the ON-direction, and a second turn-off position, in which the second mirror reflects the second light-source light beam in a second OFF-direction.

Abstract: In a liquid crystal display device, a reflecting surface is attached to a portion, which overlaps with a periphery portion of a light guiding plate where the light incident section is position in a surface on the light guiding plate side in the dispersing sheet which is positioned farthest to the light guiding plate side among a plurality of optical sheets which are positioned between the light guiding plate and a liquid crystal panel. As a result, light which is emitted from the periphery portion of the light guiding plate is returned into the light guiding plate by being reflected by the reflecting surface, and after this, is emitted as illumination light from a light emitting surface while progressing within the light guiding plate.

Abstract: A method of manufacturing a liquid crystal device having a first substrate and a second substrate facing each other with a liquid crystal layer interposed therebetween, and a sealing member formed in a peripheral portion of at least one of the substrates. The method includes forming the sealing member, disposing the liquid crystal layer inside the sealing member, and bonding the first substrate to the second substrate. In forming the sealing member, a ring-shaped portion that seals the liquid crystal layer inside the sealing member, a first sealing layer and a second sealing layer that face each other to be separated from each other are formed. In the bonding of the first substrate to the second substrate, a junction portion is formed in which the first and second sealing layers are pressed and joined outside the sealing member so as to form the ring-shaped portion.
