Liquid crystal display device and electronic equipment
View Patent ↗Disclosed herein is a liquid crystal display device including: a first substrate having a pixel area in which pixels are arranged in a matrix form; a second substrate disposed to be opposed to the first substrate; a liquid crystal layer disposed between the first and second substrates; a conductive section disposed at least on the first of the first and second substrates to apply a voltage to the liquid crystal; an organic film disposed at least over one of the first and second substrates; a sealing area adapted to hold the two substrates of the liquid crystal display device together at the peripheral portions of the first and second substrates; and an organic film-free area which is free from the organic film and extends from the inward side of the outermost end of the sealing area to the outward side of the outer periphery of the pixel area.
1. A liquid crystal display device comprising:
a first substrate having a pixel area in which pixels are arranged in a matrix form;
a second substrate disposed to be opposed to the first substrate;
a liquid crystal layer disposed between the first and second substrates;
a conductive section disposed at least on the first substrate to apply a voltage to the liquid crystal layer;
an organic film disposed at least on one of the first and second substrates, except for at least two circumferential organic film-free areas; and
a sealing area with a sealant adapted to hold the first and second substrates together at peripheral portions of the first and second substrates,
wherein,
the sealant maintains the first and second substrates in spaced apart relation,
each of the at least two circumferential organic film-free areas is an area free from the organic film and extends from no farther than the inward side of the outermost end of the sealing area to the outward side of the outer periphery of the pixel area,
each of the at least two circumferential organic film-free areas is continuous about the pixel area so as to completely surround the pixel area, and
at least one circumferential organic film-free area extends completely between the first and second substrates in a region that is free from the sealant.
2. The liquid crystal display device of claim 1 , wherein each of the at least two circumferential organic film-free areas is free from the organic film partly in the direction parallel to the main surface of the substrate and wholly in the direction vertical to the main surface of the substrate and extends from the inward side of the outermost end of the sealing area to the outward side of the outer periphery of the pixel area.
3. The liquid crystal display device of claim 2 , wherein the substrate is free from the organic film on an inorganic film between metal wirings.
4. The liquid crystal display device of claim 2 , further comprising metal wirings, wherein the substrate is free from the organic film on a top surface of the metal of the metal wirings, but not on an end surface of the metal wirings.
5. The liquid crystal display device of claim 2 , wherein the conductive section comprises a pixel electrode formed on the first substrate and an opposed electrode formed on the second substrate.
6. The liquid crystal display device of claim 5 , wherein:
first and second organic films are formed on the first and second substrates, respectively, and
the at least two circumferential organic film-free areas are formed at least in either of the first and second organic films.
7. The liquid crystal display device of claim 2 , wherein a transparent conductive section comprises a pixel electrode and opposed electrode formed on the first substrate.
8. The liquid crystal display device of claim 7 , wherein:
first and second organic films are formed on the first and second substrates, respectively, and
the at least two circumferential organic film-free areas are formed at least in either of the first and second organic films.
9. An apparatus having a liquid crystal display device, the liquid crystal display device comprising:
a first substrate having a pixel area in which pixels are arranged in a matrix form;
a second substrate disposed to be opposed to the first substrate;
a liquid crystal layer disposed between the first and second substrates;
a conductive section disposed at least on the first substrate to apply a voltage to the liquid crystal layer;
an organic film disposed at least on the first substrate, except for at least two circumferential organic film-free areas; and
a sealing area with a sealant adapted to hold the first and second substrates together at peripheral portions of the first and second substrates,
wherein,
the sealant maintains the first and second substrates in spaced apart relation,
each of the at least two circumferential organic film-free areas is an area free from the organic film and extends from no farther than the inward side of the outermost end of the sealing area to the outward side of the outer periphery of the pixel area,
each of the at least two circumferential organic film-free areas is continuous about the pixel area so as to completely surround the pixel area, and
at least one circumferential organic film-free area completely extends between the first and second substrates in a region that is free from the sealant.
10. The apparatus of claim 9 , wherein each of the at least two circumferential organic film-free areas is free from the organic film partly in the direction parallel to the main surface of the substrate and wholly in the direction vertical to the main surface of the substrate and extends from the inward side of the outermost end of the sealing area to the outward side of the outer periphery of the pixel area.
