Abstract

A display apparatus including: a main body having an opening at the front part; a backlight unit configured to generate light; and an image forming unit provided in the front part of the main body, and configured to block or transmit the light generated by the backlight unit to create an image, where the image forming unit includes: a pair of transparent substrates disposed to be opposite to each other; a cable configured to transmit image data to the pair of transparent substrates; and a pair of polarizing films respectively disposed on the outer surfaces of the pair of transparent substrates, and wherein an edge part of at least one transparent substrate of the pair of transparent substrates protrudes to connect to the cable, and at least one polarizing film of the pair of polarizing films extends to the main body in a direction in which the at least one transparent substrate protrudes.

Claims

1. A display apparatus, comprising:

a main body having an opening at a front part;

a backlight unit configured to generate light; and

an image forming unit provided in the front part of the main body, the image forming unit being configured to one of block and transmit the light generated by the backlight unit to create an image,

wherein the image forming unit comprises;

a pair of transparent substrates disposed to be opposite to each other, a first transparent substrate of the pair of transparent substrates including an edge part which protrudes along a longitudinal axis of the first transparent substrate beyond a second transparent substrate of the pair of transparent substrates;

a cable configured to transmit image data to the pair of transparent substrates, the cable being connected to the edge part of the first transparent substrate which protrudes; and

a pair of polarizing films

a first polarizing film of the pair of polarizing films disposed on an outer surface of the second transparent substrate, the first polarizing film including an extended part which extends along a longitudinal axis of the first polarizing film beyond a second polarizing film of the pair of polarizing films in a direction in which the first transparent substrate protrudes, the second polarizing film being disposed on an outer surface of the first transparent substrate,

wherein the extended part of the first polarizing film extends by a first distance from an edge of the second transparent substrate and the first distance is greater than a second distance by which the edge part of the first transparent substrate protrudes from the edge of the second transparent substrate,

wherein the image forming unit further comprises a subsidiary polarizing film attached on a surface of only the extended part of the first polarizing film, and a polarization direction of the subsidiary polarizing film is perpendicular to a polarization direction of the first polarizing film.

2. The display apparatus according to claim 1, wherein the image forming unit further comprises a support material disposed on the extended part of the first polarizing film, and configured to support the first polarizing film.

3. The display apparatus according to claim 2, wherein the support material fills space between a protruded part of the one transparent substrate and the extended part of the first polarizing film.

4. The display apparatus according to claim 1, wherein the image forming unit further comprises a dummy film disposed at an area where no cable contacts a protruded part of the first transparent substrate.

5. An image forming unit of a display, comprising:

a pair of transparent substrates disposed opposite each other on each side of an LCD layer, a first transparent substrate of the pair of transparent substrates having a protruding edge;

a cable connected to the protruding edge to transmit image data to the first transparent substrate of the pair of transparent substrates having the protruding edge; and

a pair of polarizing films, a first polarizing film of the pair of polarizing films disposed on an outer surface of a second transparent substrate of the pair of transparent substrates and the first polarizing film including an extending edge which extends along a longitudinal axis of the first polarizing film beyond a second polarizing film of the pair of polarizing films in a direction in which the protruding edge of the first transparent substrate protrudes, the second polarizing film being disposed on an outer surface of the first transparent substrate,

wherein the extended part of the first polarizing film extends by a first distance from an edge of the second transparent substrate and the first distance is greater than a second distance by which the edge part of the first transparent substrate protrudes from the edge of the second transparent substrate,

wherein the extended part of the first polarizing film has a subsidiary film attached on a surface of only the extended part of the first polarizing film and a polarization of the subsidiary film is perpendicular to the polarization of the first polarizing film.

6. The image forming unit of a display according to claim 5, wherein the cable is visually obscured from a front of the image forming unit of the display by the extended part of the first polarizing film.
