Display with Spacer Ring
First Claim
1. A display having a peripheral edge, comprising:
- first and second display layers;
a ring of adhesive sealant that is interposed between the first and second display layers; and
a ring-shaped spacer that surrounds the ring of sealant and that runs along the peripheral edge of the display.

Abstract
A display may have a layer of liquid crystal material interposed between a color filter layer and a thin-film transistor layer. A ring of adhesive sealant may surround the liquid crystal layer. Columns spacers may extend between the color filter and thin-film transistor layers through the liquid crystal layer to help ensure that the color filter and thin-film transistor layers are appropriately spaced apart from each other. A ring-shaped polymer spacer may surround the ring of adhesive sealant and may help protect display structures form exposure to etchant that is used to treat the edges of glass layers in the display. The spacer may be formed from the same layer of material that forms the column spacers. A black masking layer may be formed on the underside of the color filter layer using techniques that prevent the formation of protruding edge portions.

12. A method for forming a liquid crystal display, comprising:
-
forming a display panel having a color filter layer, a thin-film transistor layer, a layer of liquid crystal material interposed between the color filter layer and the thin-film transistor layer, a ring of adhesive sealant that retains the liquid crystal material between the color filter layer and the thin-film transistor layer, and a polymer spacer having a ring shape that surrounds the ring of adhesive sealant; grinding a peripheral edge of the color filter layer with a grinding tool; and etching the peripheral edge of the color filter layer using an etchant, wherein the polymer spacer helps prevent the etchant from reaching the ring of adhesive sealant. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A liquid crystal display, comprising:
-
a color filter layer having a glass substrate layer coated with a black masking layer; a thin-film transistor layer having a glass substrate layer with thin-film transistor circuitry; a layer of liquid crystal material interposed between the color filter layer and the thin-film transistor layer; a ring of adhesive sealant that surrounds the layer of liquid crystal material and retains the liquid crystal material between the color filter layer and the thin-film transistor layer; and a polymer spacer ring that surrounds the ring of adhesive sealant, wherein the ring of adhesive sealant is formed from a first material and the polymer spacer ring is formed from a second material that is different than the first material. - View Dependent Claims (20, 21)
