ABSTRACT:
The invention relates to a display apparatus including a first substrate supporting an array of light modulators, a second substrate separated from the first substrate by a gap, a fluid substantially filling the gap, sealing material joining the first substrate to the second substrate, and a bubble trapping region within a space enclosed by the sealing material for substantially constraining a location of a bubble trapped within the gap. In some embodiments, the bubble trapping region extends along a majority of a side of at least one of the substrates. In some embodiments, the fluid has a viscosity less than 70 centipoise.
