Method and device for parting glass substrate, liquid crystal panel, and liquid crystal panel manufacturing device
First Claim
1. A method of cutting apart a glass substrate having a deposited film formed thereon, comprising the steps of:
- removing strip-shaped portions of the deposited film so as to expose strip-shaped regions on the substrate; and
forming cracks so as to permit the glass substrate to be cut apart along the strip-shaped regions exposed thereon by the glass substrate exposing means, and cutting the glass substrate apart along the cracks.

Abstract
A method for cutting apart a glass substrate is provided whereby scribing of the glass substrate is possible without being affected by the presence or thickness of a deposited film formed thereon and without scratching the deposited film. To treat a glass substrate (1) having a deposited film (1a), such as a thin film or resin film, formed on one surface thereof, there are provided a shaving means (202), which is a blade that removes strip-shaped portions of the deposited film (1a) to expose strip-shaped regions on the glass substrate (1), and a wheel cutter (14a) that forms scribed lines along the strip-shaped regions exposed on the glass substrate (1). The glass substrate (1) is cut apart along the scribed lines.

18. An apparatus for cutting apart a glass substrate, the apparatus including a workpiece stage on which a glass substrate having a deposited film formed thereon is placed, securing means for securing the glass substrate in a predetermined position on the workpiece stage, crack forming means for forming cracks on the glass substrate so as to permit the glass substrate to be cut apart along the cracks, and actuating means for moving the crack forming means to a predetermined position, the apparatus cutting apart the glass substrate into a plurality of blocks along the cracks, comprising:
-
a glass substrate exposing means for removing strip-shaped portions of the deposited film so as to expose strip-shaped regions on the glass substrate, wherein the cracks are so formed that the glass substrate is cut apart along the strip-shaped regions exposed thereon by the glass substrate exposing means. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)

38. A liquid crystal panel composed of a pair of substrate cells bonded together with liquid crystal sealed in between and with polarizer plates bonded to outer surfaces of the substrate cells,
wherein at least one end of one of the substrate cells protrudes from at least one end of the other of the substrate cells so as to form a protruding portion, connection terminals by way of which the liquid crystal panel is driven is formed on an inner surface of the protruding portion, and the polarizing plate so extends as to cover an outer surface of the protruding portion.

40. A liquid crystal panel composed of a pair of substrate cells bonded together with liquid crystal sealed in between and with polarizer plates bonded to outer surfaces of the substrate cells,
wherein edges of the polarizer plates are so formed as to have a vertical section that becomes thinner and thinner toward the substrate cells.
