Embodiment Construction

[0043] Thereafter, the present invention will be described by way of embodiments with reference to the accompanying drawings. In the drawings for describing examples of the present invention, elements whose functions are the same as those in conventional examples are denoted by the same reference numerals.

[0044] (Example 1)

[0045] FIG. 1 shows an equivalent circuit of an active matrix substrate 11 in a display panel according to Example 1 of the present invention.

[0046] The active matrix substrate 11 includes a transmissive substrate 1 made of a glass plate or the like, and a plurality of signal lines 2 and a plurality of scanning lines 3 crossing each other through insulating films (not shown). Active matrix substrate 11 also includes TFT 4 and pixel electrodes 5 as switching elements in the vicinity of intersections between signal lines 2 and scanning lines 3 . A display area is defined by a plurality of pixel electrodes 5 arranged in a matrix layout. Each pixel e...

Abstract

A display panel of the present invention includes: a first substrate and a second substrate opposing each other with a display medium interposed therebetween; a plurality of signal lines and a plurality of scanning lines provided on the first substrate to cross each other and be insulated from each other; and a plurality of pixel electrodes each provided in a vicinity of an intersection between one of the plurality of signal lines and one of the plurality of scanning lines so as to be connected to the one of the plurality of signal lines and the one of the plurality of scanning lines via a switching element, while the plurality of pixel electrodes define a display region of the display panel. At least one of each of the plurality of signal lines and each of the plurality of scanning lines has a high resistance portion proximate an end thereof outside the display region. The high resistance portion is interposed at least partially between the first substrate and the second substrate.

Description

[0001] This application is a divisional application of the patent application submitted on March 26, 1998, with the application number 98105187.1 and the title of the invention "display panel". technical field [0002] The present invention relates to display panels such as liquid crystal display panels used in televisions, personal computers, word processors, OA (office automation) devices, and the like. Background technique [0003] This liquid crystal display panel has a structure in which a pair of substrates are arranged such that they are opposed to each other while interposing a liquid crystal layer as a display medium. One of the pair of substrates is an active matrix substrate in which a plurality of signal lines and a plurality of scanning lines are arranged so as to cross each other through insulating films. A pixel electrode is disposed near the intersection of the signal line and the scanning line, and is connected to the signal line and the scanning line throug...
