Embodiment Construction

[0051] Next, the present invention will be described in detail.

[0052] FIG. 1 is a diagram showing an embodiment of an electrophoretic display device 1 of the present invention. Reference numeral 1 in FIG. 1 denotes an electrophoretic display device. This electrophoretic display device 1 includes a rectangular display device 4 (electro-optic panel) in plan view and a single protective film 5 covering the entire display device 4 . The display device 4 includes a first substrate 2 having segment electrodes 6 (drive electrodes) and a second substrate 3 having a common electrode 7 arranged to face each other, and an electrophoretic layer 13 sandwiched between the substrates 2 and 3 . Furthermore, the electrophoretic layer 13 has a plurality of microcapsules 10 enclosing the electrophoretic dispersion liquid 11 including the liquid phase dispersion medium 9 and the electrophoretic particles 8 . The electrophoretic display device 1 of the present invention performs display by ch...

Abstract

The invention provides an electrophoretic display device which has excellent wet resistance and can prevent water content and so on in the air from immerging into the display device, and an electronic equipment. The invention is an electrophoretic display device (1), which has a display device (4) with an electrophoretic layer (13) which has electrophoretic particles (8) and the electrophoretic dispersed liquid (11) of a liquid-phase disperse medium (9) dispersing the electrophoretic particles. The display device (4) is coated by a piece of folded film (5), and the end (5a) and the end (5b) are mutually jointed at an overlapping sealed part (20).

Description

technical field [0001] The present invention relates to an electrophoretic display device and electronic equipment. Background technique [0002] Conventionally, there is known an electrophoretic display device having an electrophoretic dispersion liquid including a liquid-phase dispersion medium and electrophoretic particles and utilizing the phenomenon that the distribution state of the electrophoretic particles is changed by applying an electric field, thereby changing the optical properties of the electrophoretic dispersion liquid. Variety. [0003] Since such an electrophoretic display device does not require a backlight, cost reduction, thickness reduction, and the like can be achieved. Moreover, it has display memory in addition to having a wide viewing angle and high contrast, so it is attracting attention as a next-generation display device. [0004] In addition, among such electrophoretic display devices, there is known an electrophoretic display device in which ...
