Problems solved by technology

[0006] However, when the surface of the liquid crystal panel for color tone correction is pressed with a finger, the glass is deformed together with the spacer material, and the thickness of the glass is partially reduced. As a result, the optical compensation relationship of the liquid crystal panel for color tone correction is broken, and the display has Intrinsic disadvantage of extreme drop in quality
In addition, the gap length between the two glasses is generally on the order of several μm, and there is another disadvantage that the spacer material used to maintain the gap length is easily permanently deformed due to aging, and the durability decreases.
The current situation is that as long as these problems are not solved, it will be difficult to realize practical application

Embodiment Construction

[0035] Hereinafter, embodiments of the liquid crystal display element of the present invention will be described with reference to the drawings. figure 1 (A) is a schematic cross-sectional view of the liquid crystal display element 1 . In addition, unclear points in the correspondence relationship between each constituent part of the liquid crystal display element 1 and the invention-specific matters in the claimed scope are collectively shown in the explanatory column of the above-mentioned reference numerals.

[0036] The liquid crystal display element 1 enumerated here has: the liquid crystal display unit 10 of DSTN type (Double Layer, double-layer type); phase deviation. As described above, the compensation unit 20 not only improves the optical characteristics of the liquid crystal display unit 10 but also functions as a capacitive touch panel. Hereinafter, details of each constituent unit will be described.

[0037] In addition, the liquid crystal display element 1 is a ...

Abstract

Provided is a liquid crystal display element wherein high display qualities and low cost are both achieved while having a function as a capacitance-type touch panel. The liquid crystal display element is provided with a liquid crystal display cell (10), and a compensating cell (20) arranged to face the liquid crystal display cell (10) so as to improve optical characteristics of the liquid crystal display cell (10). At least a transparent electrode group (28) of the touch panel is formed on compensating glass bodies (21, 22) of the compensating cell (20) so as to have the compensating cell (20) function as the capacitance-type touch panel. The compensating cell (20) has a structure wherein a space between the compensating glass body (21) and the compensating glass body (22) is filled with a liquid crystal (26), and the transparent electrode group (28) is arranged on the inner facing surfaces of the compensating glass bodies (21, 22), respectively.

Description

technical field [0001] The present invention relates to a liquid crystal display element having both functions of a liquid crystal module and a touch panel. Background technique [0002] As such a conventional example, there is a liquid crystal display element including: a liquid crystal panel for display; and a liquid crystal panel for color tone correction arranged opposite to the liquid crystal panel for display, and the liquid crystal panel for color tone correction also serves as a resistive touch panel. [0003] Regarding the liquid crystal panel for color tone correction, two glasses are arranged facing each other with a spacer interposed therebetween, and liquid crystal is sealed between the two glasses. Transparent conductive films serving as movable electrodes and fixed electrodes of the touch panel are respectively pasted on the inner facing surfaces of the two glasses. [0004] That is, when the surface of the liquid crystal panel for color tone correction is pr...
