Abstract

An electrophoretic display device (100) having improved frontal reflectance includes a first substrate (110) including a first electrode (112) of a transparent material having a first optical pattern (111a), a second substrate (120) opposing the first substrate (110) and including a plurality of second electrodes (122), a spacer (130) interposed between the first and second substrates (110,120) to define a space between the first and second substrates (110,120), and a image display layer (140) formed in the space formed by the first and second substrates (110,120) and the spacer (130) to display an image by an electric field generated between the first and second electrodes (112,122).

Description

[0001] This application claims the priority of Korean Patent Application No. 2006-72281 filed with the Korean Intellectual Property Office on July 31, 2006 and Korean Patent Application No. 2007-21261 filed with the Korean Intellectual Property Office on March 5, 2007, respectively, This application is hereby disclosed in its entirety by reference. technical field [0002] The present invention relates to an electrophoretic display device, and more particularly, to an electrophoretic display device with improved front reflectance. Background technique [0003] Electrophoretic display devices display visible images by arranging charged pigment particles dispersed in a liquid medium with an applied electric field. [0004] FIG. 1 is a cross-sectional view showing a conventional electrophoretic display device. As shown in FIG. 1 , an electrophoretic display device 1 is realized by two facing substrates 10 and 20 on which electrodes 12 and 22 are respectively formed. An image ...
