A touch-type liquid crystal display apparatus with a built-in contact, includes a substrate support structure supporting a first substrate and a second substrate respectively. The substrate support structure includes a pillar-shaped spacer formed on an opposing surface of the second substrate, and a base region formed on an opposing surface of the first substrate and having a front end with which a front end of the pillar-shaped spacer is in contact. A contact point protrusion is also formed on the opposing surface of the second substrate by using the same material as that of the pillar-shaped spacer.

Touch-type liquid crystal display apparatus with built-in contact

A liquid crystal display panel includes a pixel electrode to apply a voltage to a liquid crystal layer disposed between the pixel electrode and an opposed electrode, a thin film transistor connected to the pixel electrode, a scanning line to supply a gate signal to the thin film transistor, a first coordinate detection line disposed parallel to the scanning line, a first coordinate detection electrode formed closer to the liquid crystal layer than the scanning line and the first coordinate detection line, and a first insulating film formed as a layer between the first coordinate detection line and the first coordinate detection electrode. The first insulating film is provided with a contact hole to electrically connect the first coordinate detection line and the first coordinate detection electrode.

Liquid crystal display panel and touch panel

A liquid crystal display panel in which coordinate detection electrodes are formed on a first substrate and protruding contact portions are formed on a second substrate as a touch panel function includes a conversion circuit formed therein. The conversion circuit subjects information indicative of whether the protruding contact portions are in contact with the coordinate detection electrodes to parallel/serial conversion to output the converted information to the coordinate detection circuit.

Liquid crystal display panel and liquid crystal display apparatus

A liquid crystal display device includes first and second substrates arranged to face each other with a predetermined gap, and a liquid crystal layer sealed between the first and second substrates. The first substrate includes pixel electrodes and thin-film transistors connected with the pixel electrodes. The transistors are turned on based on a scanning signal from scanning lines to electrically connect the pixel electrodes to signal lines. The second substrate has an opposed electrode, which forms pixels in areas facing the pixel electrodes. The device also has a touch input contact point provided on either the pixel electrodes or the opposed electrode to correspond to a previously selected pixel. The contact point protrudes at a height smaller than the gap between the first and second substrates and is brought into conduction by flexural deformation caused by a pressing force of a touch onto the first or second substrates.

A resistive film type touch panel includes first and second resistive films respectively provided on the inner surfaces of a pair of substrates on the touch side and the opposite side, protruding contacts which are provided on the first resistive film so as to protrude to a predetermined height, and come into contact with the second resistive film upon bending/deformation of the touch-side substrate by a touch to electrically connect the touch-side substrate to the second resistive film, insulating spacers which are arranged between the substrates except the positions of the protruding contacts, and define the space between the substrates to a height higher than that of protruding contacts, and a liquid or liquid crystal sealed in the space between the substrates. This arrangement reduces the bending/deformation amount of the touch-side substrate and the refraction of transmitted light at a portion bent/deformed by a touch on the touch-side substrate.
