Problems solved by technology

In such a structure, a step is formed between the case and the operation surface of the touch panel (refer to FIG. 20 ), and the design integrated with the case cannot be adopted, so the degree of freedom in design decreases.

Abstract

The present invention relates to an input device and manufacturing method thereof and an electro-optical device. The provided input device can improve the concept design performance of the electronic appliance with the input unit, and can also improve the reliability ideally.The input device of the invention (40A) is characterized in that: an input panel (a touching panel) (4) having a cover element (45) of a containing part (45a) for holding the touching panel (4), and having a surface (4s) at side of the input operation of the touching panel (4) in the containing part (45a) and a bonding film (a flexibility element) (30) at side surface (45s) of the input operation surface of the cap element (45).

Description

technical field [0001] The present invention relates to input devices, electro-optic devices, and electronic equipment. Background technique [0002] In recent years, with the popularization of small information electronic devices such as personal digital assistants (PDAs) and palmtop computers, liquid crystal devices in which a touch panel is mounted on a liquid crystal panel as an input device are widely used (for example, refer to Patent Document 1). [0003] [Patent Document 1] JP-A-2003-43450 [0004] However, when a liquid crystal device including a touch panel is used as a display unit of an electronic device, the touch panel must be exposed from the surface of the case, so the case usually presses and supports the frame portion of the touch panel. In such a structure, a step is formed between the case and the operation surface of the touch panel (see FIG. 20 ), and the design integrated with the case cannot be adopted, so the degree of freedom in design is reduced. ...
