Abstract

An electro-optical device includes a panel having an electro-optical material with terminals in an end portion thereof, a wiring board connected to the terminals, a protective member fixed to the panel, a space portion defined by the end portion of the panel and the protective member, and a space filling member provided in the space portion between the end portion of the panel and the protective member.

Claims

1. An electro-optical device, comprising:

an electro-optical panel having an electro-optical material, the electro-optical panel including;

a first substrate;

a second substrate disposed opposite the first substrate, the second substrate having an extension portion that extends outward relative the first substrate and includes a plurality of terminals;

a polarizer disposed on the first substrate;

a flexible printed circuit board connected to the plurality of terminals;

a protective member disposed on the polarizer and extending outward from the polarizer to overlap the first substrate, the extension portion of the second substrate, and the flexible printed circuit board such that a space is defined between the protective member, the second substrate, and an end of the flexible printed circuit board connected to the terminals, and the polarizer; and

a tape having a first end disposed directly between and overlapping the protective member and the flexible printed circuit board, the tape extending into the space and having a second end directly adhered to the extension portion of the second substrate such that a gap exists between the second end of the tape and the protective member, and another gap exists between the flexible printed circuit board, a portion of the tape proximate the first end, and the extended portion of the second substrate.

2. The electro-optical device of claim 1, further comprising:

a casing fixed to the panel; and

the protective member is provided in the casing to protect the panel.

3. The electro-optical device according to claim 2, wherein the first end of the tape is fixed to the protective member.

4. An electronic apparatus having mounted thereon the electro-optical device according to claim 1.
