Abstract

The present invention provides an electro-optical device which prevents the shadow of a second optical panel from being cast on a first optical panel with a simple structure, and electronic equipment including the electro-optical device. It is characterized in that it comprises: a first optical panel (10) comprising a pair of substrates (11, 12) sandwiching an electro-optic substance (14); Simultaneously, be configured to overlap with the 1st optical panel (10) planar view, the 2nd optical panel (20) smaller than the 1st optical panel (10) planar dimension; Illumination device (30), it has: the light source ( 31), arranged between the first optical panel (10) and the second optical panel (20), and make the light emitted from the light source (31) incident on the first optical panel (10) and the second optical panel (20) respectively A light guide member (32); a light absorbing member (40) disposed between the first optical panel (10) and the second optical panel (20) outside the display area of ​​the second optical panel.

Description

technical field [0001] The present invention relates to an electro-optical device used in, for example, a mobile phone, and more particularly, to an electro-optical device having optical panels on both the front and rear surfaces, and electronic equipment having the electro-optical device. Background technique [0002] In recent years, electro-optical devices such as liquid crystal display devices have been widely used as display units in electronic devices such as mobile phones, portable computers, and video cameras. As such an electro-optical device, it has been proposed to arrange two liquid crystal devices back-to-back on information terminals such as mobile phones and PDAs (Personal Digital Assistant) (for example, refer to Patent Document 1 and Patent Document 2). . [0003] In such an electronic device, the first liquid crystal panel and the second liquid crystal panel are arranged at a predetermined interval, and between the first liquid crystal panel and the second...
