Abstract

The present invention provides an electro-optical device for displaying sharp color images at low cost. The electro-optical device can include a first substrate, a second substrate facing the first substrate, an electro-optical layer which is disposed between the first and second substrates and which includes electrophoretic particles and a dispersion medium, and a colored layer which is located at a position corresponding to the electro-optical layer and which includes at least one color element, wherein at least a part of the dispersion medium has substantially the same color as that of the color element.

Claims (12)

1. A method for forming a colored layer comprising:

changing the relative positional relationship between a porous member and a head discharging a material; and

discharging the material onto the porous member,

the material including a coloring material having a size smaller than that of pores of the porous member.

2. The method for forming a colored layer according to claim 1 , the coloring material including a dye.

3. A method for manufacturing an electro-optical device having a plurality of dot regions, comprising:

changing a relative positional relationship between a head discharging a material and a substrate provided with porous members corresponding to the dot regions; and

discharging the material onto the porous member from the head,

the material including a coloring material having a size smaller than that of pores of the porous member.

4. The method for manufacturing an electro-optical device according to claim 3 ,

the material including electrophoretic particles, and

the electrophoretic particles having a diameter larger than that of the pores provided in the porous member.
