摘要： PROBLEM TO BE SOLVED: To provide a display device suppressed in the spread of a particle group at a first electrode side. SOLUTION: When transferring a particle group 40 arranged at a back substrate 22 side to a display substrate 20 side, first voltages are applied to a display electrode 24 and a pixel electrode 26 provided at a position corresponding to a pixel which transfers the particle group 40 from the back substrate 22 side to the display substrate 20 side among a plurality of the pixel electrodes 26, so that a potential difference enables the particle group 40 to be transferred from the back substrate 22 side to the display substrate 20 side. A voltage application part 16 applies a second voltage to a projection electrode 34 concurrently with the application of the first voltage or before the application of the first voltage. The second voltage has the same polarity as that of the voltage applied to the pixel electrode 26 by the application of the first voltage, and the absolute value of the potential difference from the display electrode 24 is higher than 0 and equal to or lower than the absolute value of the smallest potential difference among the potential differences between the display electrode 24 and the pixel electrodes 26 to which the first voltage is applied.

摘要： PROBLEM TO BE SOLVED: To provide a display medium that improves color density while suppressing color remaining and color unevenness without lowering a display speed, and to provide a display device. SOLUTION: Since projection pieces of a projection group 25 provided on a substrate opposite surface of a display substrate 20 are arranged projecting in a substrate opposite surface direction, particles of a moving particle group 34 are easily stuck and restricted on its outer circumferential surface one over another when viewed from a visual field direction, and the color density is improved. Further, the projection group 25 is formed on the substrate surface by, for example, a molding method etc., without varying in shape and in position, so variation in restricted particle density is suppressed, thereby restricting color unevenness. Then the projection group 25 is arranged projecting in the substrate opposite surface direction, so there are less binding points (contact portions) between projection pieces 25A to be an obstacle to movement of the moving particle group 34 and the moving speed of the particles is not reduced to suppress a decrease in display speed. Further, color remaining is also suppressed. COPYRIGHT: (C)2009,JPO&INPIT
摘要翻译：解决的问题：提供一种在不降低显示速度的同时抑制色彩残余和颜色不均匀性的同时提高色彩浓度并提供显示装置的显示介质。解决方案：由于设置在显示基板20的与基板相反的表面上的突起组25的突出片在基板的相对表面方向上突出设置，因此移动的微粒组34的颗粒容易被粘附并限制在其外周从视场方向观察时，其表面一个接一个，并且颜色密度提高。此外，突起组25通过例如成型方法等在基板表面上形成，而不会改变形状和位置，从而抑制了限制粒子密度的变化，从而限制了颜色不均匀。然后，投影组25在基板的相对表面方向上突出设置，因此突出片25A之间的接合点（接触部分）较少，成为移动颗粒组34移动的障碍物，并且颗粒的移动速度不是减少以抑制显示速度的降低。此外，还抑制着色。版权所有（C）2009，JPO＆INPIT
