Abstract
The present invention provides a display device comprising a display panel and a conductive pattern, in which the conductive pattern comprises an irregular pattern.
Claims15
A display device, comprising:
- a display panel, and
- a conductive pattern,
- wherein the conductive pattern comprises an irregular pattern,
- wherein the conductive pattern consists of copper, aluminum, silver, Mo, Ni, Cr, or Ti,
- wherein the irregular pattern comprises a pattern that is formed of closed figures in which distribution is continuous and a ratio of standard deviation with respect to an average value of areas of the closed figures (area distribution ratio) is 2% or more, or a pattern in which, when a straight line that intersects the conductive pattern is drawn, a ratio of standard deviation with respect to an average value of distances between adjacent intersection points of the straight line and the conductive pattern (distance distribution ratio) is 2% or more,
- wherein the display device comprises at least one of a heating element in which the conductive pattern is provided on at least one surface of a transparent substrate;
- a phase difference compensation film in which the conductive pattern is provided on at least one surface thereof;
- and a light guide plate in which the conductive pattern is provided on at least one surface thereof;
- and
- wherein the display device additionally comprises a backlight unit provided on a rear surface side of the display panel, and the conductive pattern is directly formed on a front surface or rear surface of the backlight unit.

A display device, comprising:
- a display panel, and
- a conductive pattern,
- wherein the conductive pattern comprises an irregular pattern,
- wherein the conductive pattern consists of copper, aluminum, silver, Mo, Ni, Cr or Ti,
- wherein the display device comprises a polarizing film and a polarizing film protective film provided on at least one surface of the polarizing film, and the conductive pattern is provided on at least one side or both sides of the polarizing film protective film,
- wherein the display panel further comprises a bus bar, and the conductive pattern comprises a conductive heating pattern which is electrically connected to the bus bar and a conductive non-heating pattern which is not electrically connected to the bus bar,
- wherein the display device further comprises an edge-type backlight unit,
- wherein the conductive non-heating pattern is formed such that a density is higher in a region closer to a light source of the edge-type backlight unit than a density in a region farther from the light source of the edge-type backlight unit, and
- wherein the conductive heating pattern is formed such that the density is higher in a region farther from the light source of the edge-type backlight unit than the density in a region closer to the light source of the edge-type backlight unit.
