Title:
LIQUID CRYSTAL DISPLAY DEVICE WITH TOUCH PANEL
Document Type and Number:
Japanese Patent JPH0784705
Kind Code:
A
Abstract:

PURPOSE: To make a contrast more excellent than that of a liquid crystal display device with a touch panel using an exclusive substrate for a flexible electrode by using a polarizing plate constituting a liquid crystal display panel for the substrate for the movable electrode of the touch panel.

CONSTITUTION: A flexible electrode 3 consists of a substrate 5 having flexibility and a transparent conductive film 6 such as an ITO formed on the rear of the substrate 5, and a polarizing plate 14 of a surface side constituting a liquid crystal panel 2 is used for the substrate 5. Also, a phase difference plate 21 is arranged so as to be separated from the flexible electrode (a substrate for a flexible electrode) 3 of a touch panel 1, that is, they are arranged so as not to be integrated, so that the thickness of the flexible electrode 3 can be made thin, and the flexibility can be improved. When the flexibility is improved, the cracking of the transparent conductive film 6 formed on the surface of the flexible electrode 3 can be suppressed, and also the writing durability of the flexible electrode 3 can be improved. Moreover, the transparent conductive film is not formed on the phase difference plate 21, so that the characteristic deterioration of the phase difference plate 21 can be prevented.
