Patent ID: 7830595

Claim:
An electro-optical device comprising: an electro-optical panel having a first side and a second side, the second side being formed on an opposite side of the electro-optical panel than the first side; a protective member having a light-transmitting substrate mounted on the electro-optical panel adjacent to the first side; a backlight disposed adjacent to the second side of the electro-optical panel; and a holding member including a casing housing the electro-optical panel and the backlight, wherein: the protective member has: a thick portion where a thickness of the light-transmitting substrate is large; a thin portion where the thickness of the light-transmitting substrate is small, the thin portion extending around an outer circumference of the light-transmitting substrate; and a step portion extending a distance (D) between a top surface of the thick portion and a top surface of the thin portion of the light-transmitting substrate, wherein the top surface of the thick portion is positioned farther away from the backlight than the top surface of the thin portion, wherein the holding member has a fitting portion nested in the step portion of the protective member which extends the distance (D) and is positioned above the top surface of the thin portion of the light-transmitting substrate such that the thin portion of the light-transmitting substrate is positioned between the fitting portion and the backlight and a top surface of the fitting portion is flush with the top surface of the thick portion of the light-transmitting substrate, and wherein the light-transmitting substrate and the electro-optical panel are bonded to each other with an adhesive layer.
