LIQUID CRYSTAL DISPLAY DEVICE
First Claim
1. A liquid crystal display device comprising:
- a liquid crystal display panel including liquid crystals sandwiched between a first substrate and a second substrate,wherein;
when a side of the first substrate or the second substrate facing the liquid crystals is defined as an inner side of the first substrate or an inner side of the second substrate and a side of the first substrate or the second substrate opposite to the side facing the liquid crystals is defined as an outer side of the first substrate or an outer side of the second substrate,a first electrode is formed on the outer side of the first substrate as the first electrode is extended in a first direction, a second electrode is formed on the inner side of the first substrate or the second substrate, the second electrode being extended in a direction perpendicular to the first direction, and a touch panel function is provided on the liquid crystal display panel;
the first electrode is formed of a metal or alloy, and a protective film is formed to cover the first electrode; and
on the outer side of the first substrate, a groove is formed between an end portion of the protective film and the first electrode in parallel with an edge of the first substrate.

Abstract
The detection speed of a touch is improved and the reliability of a touch panel electrode formed on the outer side of a glass substrate is improved. A liquid crystal display device is provided in which a first electrode is formed on the outer side of a counter substrate as the first electrode is extended in a first direction. A second electrode extended in a direction perpendicular to the first direction is formed on the inner side of a TFT substrate. A touch panel function is provided on a liquid crystal display panel. The first electrode is formed of a metal or alloy. A protective film is formed to cover the first electrode. On the outer side of the first substrate, a groove is formed between the end portion of the protective film and the first electrode in parallel with the edge of the counter substrate.
