Abstract
An image display panel is prepared which has in an in-plane thereof an image display area for displaying an image and a framing area surrounding the image display area. Light shielding ink is supplied from an ink supply source to at least a partial surface area of the framing area of the image display panel. In this case, the ink supply source is made not in contact with the image display panel. Even if the frame structure of an image display device such as a liquid crystal display is made narrow, the image quality in a peripheral area of the image display area becomes hard to be lowered.
Claims20
A method of manufacturing an image display device, comprising the steps of:
- preparing an image display panel having in an in-plane thereof an image display area for displaying an image and a framing area surrounding the image display area;
- and
- supplying light shielding ink from an ink supply source to at least a partial surface area of the framing area of the image display panel, the light shielding ink being coated on the partial surface area without bringing the ink supply source into contact with the image display panel.
A method of manufacturing an image display device that includes a first substrate positioned above a second substrate, said method comprising the steps of:
- preparing an image display panel having in an in-plane thereof an image display area for displaying an image and a framing area surrounding the image display area, wherein the image display panel has a step near at least two peripheral edges of the framing area, where each of said steps is defined by an edge of said first substrate that terminates inwardly of the associated edge of said second substrate;
- and
- supplying light shielding ink from an ink supply source to at least a partial surface area of the framing area of the image display panel, the light shielding ink being coated on the partial surface area without bringing the ink supply source into contact with the image display panel, wherein the light shielding ink is coated to overlap at least one of said steps such that the light shielding ink at said step overlaps a portion of an upper surface of the first substrate, a portion of a peripheral side edge of the first substrate and a portion of an upper surface of the second substrate.
A method of manufacturing an image display device comprising the steps of:
- preparing an image display panel having in an in-plane thereof an image display area for displaying an image and a framing area surrounding the image display area;
- and
- supplying light shielding ink from an ink supply source to at least a partial surface area of the framing area of the image display panel, the light shielding ink being coated on the partial surface area without bringing the ink supply source into contact with the image display panel;
- wherein the supplying step includes blowing light shielding ink droplets from said ink supply source while moving said ink supply source relative to the image display panel, and further wherein the supplying step also includes:
- a first step of supplying a light shielding ink droplet to each of a plurality of coating target points disposed along a virtual straight line parallel to a first direction on a surface of the image display panel;
- and
- a second step of moving the ink supply source relative to the image display device to supply a light shielding ink droplet to each of a plurality of coating target points obtained by displacing the plurality of coating target points disposed along the virtual straight line in a second direction that obliquely intersects the first direction.
