Claim Text:
1. An electrowetting display device comprising: a first substrate; a hydrophobic surface on the first substrate; an electrowetting oil on the hydrophobic surface and a fluid that includes an electrolyte on the electrowetting oil; an electrode under the hydrophobic surface; a thin film transistor coupled to the electrode and a voltage source; a second substrate; and an ultraviolet (UV) curable epoxy glue in contact with the fluid and configured to couple the second substrate to the first substrate, wherein the UV curable epoxy glue comprises silica particles in a range of 1-6% mass fraction of silica, wherein the silica particles introduce a yield stress into the UV curable epoxy glue such that the UV curable epoxy glue minimally deforms when in contact with the second fluid.
