Display with Column Spacer Structures

摘要

A display may have a color filter layer and a thin-film transistor layer. A layer of liquid crystal material may be located between the color filter layer and the thin-film transistor layer. Column spacers may be formed on the color filter layer to maintain a desired gap between the color filter and thin-film transistor layers. Support pads may be used to support the column spacers. The column spacers and support pads may have comparable thicknesses. Different column spacers may be located at different portions of the support pads to allow the support pad size to be reduced while ensuring adequate support.

主权项

1. A display, comprising:
a color filter layer having an inner surface and an opposing outer surface, wherein the color filter layer includes a column spacer on the inner surface; a thin-film transistor layer having a column spacer support pad for supporting the column spacer, wherein the column spacer support pad and the column spacer have heights that are within 30% of each other; a layer of liquid crystal material between the color filter layer and the thin-film transistor layer.
