Abstract

A film for testing a liquid crystal display (LCD) panel, a test device for testing a LCD panel, and a method of manufacturing the test device are provided. The test device includes a film configured to have first lines and second lines formed thereon wherein the first lines receive test signals and the second lines are disposed apart from the first lines, branch the test signals received from the first lines into n (n is a natural number) signals and transmit the branched test signals to corresponding input lines of the LCD panel; a line connection unit configured to be formed on a substrate and include metal lines to transmit signals received via the first lines to the respective corresponding second lines; and bumps configured to electrically connect the first lines and the second lines to the corresponding metal lines.

Description

technical field [0001] The present invention relates to a film for testing a liquid crystal display (LCD) panel, a test device for testing an LCD panel and a method for manufacturing the test device, and more particularly relates to a film for testing a liquid crystal display (LCD) panel that can reduce manufacturing processes and costs A film for testing an LCD panel, a test device for testing an LCD panel, and a method of manufacturing the test device. Background technique [0002] As the use of display devices increases in various fields, research on liquid crystal display panels mounted on display devices and methods for testing LCD panels has been actively conducted. A normal liquid crystal panel subjected to defect inspection has modules mounted thereon, and can be used for a display device such as a television, a monitor, or the like. [0003] FIG. 1 is a diagram describing an example of a related art testing device for testing an LCD panel. figure 2 is the descript...
