发明名称 LIQUID CRYSTAL DISPLAY DEVICE WITH INPUT TOUCH PANEL
摘要 <p>PROBLEM TO BE SOLVED: To prevent a liquid crystal cell from being brought into contact with the lower substrate of the liquid crystal cell even when the liquid crystal cell is distorted, and to prevent color non-uniformity from being generated by providing a clearance between the back face of a liquid crystal panel and a member arranged at the lower part of the back face side of the liquid crystal panel. SOLUTION: The upper substrate of a touch panel 1 comprises a film substrate whose width is almost 0.1mm in which a transparent conductive thin film is provided on a transparent film such as polyester and a polycarbonate. The lower substrate of the touch panel 1 comprises a polycarbonate whose width is almost 1mm. A spacer with a first diameter (almost 20μm) is arranged between the upper substrate and the lower substrate of the touch panel. The touch panel 1 is adhered to the liquid crystal display panel 50 with an acrylic adhesive sheet layer 2 without any substrate whose thickness is almost 0.5mm and whose peel adhesive intensity is almost 10g. Then, a clearance 5 whose thickness is 2mm is provided between the back face of the liquid crystal display panel 50 and a driving circuit substrate 6 arranged at the lower part of the back face side of the liquid crystal display panel 50.</p>
