Claims
- 1. A liquid crystal color-display panel, comprising:
- a substrate which bears thereon a color filter having thereon a passivation layer, said passivation layer having thereon a first electrode:
- another substrate which bears thereon a second electrode intersecting the first electrode so as to form a pixel area at the intersecting area; and
- a liquid crystal being disposed between said substrates at a film thickness of 1-2 .mu.m in said pixel area, wherein:
- said substrates are mutually adhered so as to form different cell gaps in said pixel area and in the peripheral area,
- the diameter T of a first gap-retaining material contained in sealant provided in the peripheral area satisfies a relationship:
- t.sub.1 +(t.sub.2 /2).ltoreq.T
- in which t.sub.1 is the cell gap of the pixel area and t.sub.2 is the thickness of said color filter,
- a second gap-retaining material is provided in a space between said pixel area and a sealed portion of the peripheral area, and
- an edge portion of the color filter is extended to a position of a distance of 1.2-5 mm from a position at the sealed portion of the peripheral area.
- 2. A liquid crystal color-display panel according to claim 1, wherein a diameter of said second gap-retaining material is equal to the diameter T.
- 3. A liquid crystal color-display panel according to claim 1, wherein said T, t.sub.1 and t.sub.2 and the thickness t.sub.3 of said passivation layer satisfy a relationship:
- t.sub.1 +(t.sub.2 /2).ltoreq.T.ltoreq.T.sub.1 +t.sub.2 +t.sub.3.
- 4. A liquid crystal color-display panel according to claim 1, wherein T, t.sub.1 and t.sub.2 satisfy a relationship:
- t.sub.1 +(t.sub.2 /2).ltoreq.T.ltoreq.t.sub.1 +t.sub.2.
- 5. A liquid crystal color-display panel according to claim 1, wherein said liquid crystal is a chiral smectic liquid crystal.
- 6. A liquid crystal color-display panel according to claim 1, comprising a plurality of said color filter and a mask in an area between adjoining color filters.
- 7. A liquid crystal color-display panel according to claim 6, wherein said mask is a metal film.
