Abstract
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.
Claims18
A touch-type liquid crystal display apparatus with a built-in contact, comprising:
- first and second substrates which are arranged to face each other;
- liquid crystal which is sandwiched between the first substrate and the second substrate;
- at least one opposed electrode which is provided on an opposing surface of the second substrate facing the first substrate;
- a plurality of pixel electrodes which is provided on the first substrate to face the opposed electrode, so that a plurality of pixels are formed between the pixel electrodes and the opposed electrode;
- a contact point protrusion which is formed on the opposing surface of the second substrate at a first pixel of the plurality of pixels;
- a pillar-shaped spacer which is formed on the opposing surface of the second substrate at a second pixel of the plurality of pixels, the pillar-shaped spacer being made of the same material as that of the contact point protrusion;
- a contact point region which is provided on the first substrate, wherein the contact point region faces the contact point protrusion;
- and
- a base region which is provided on the first substrate, wherein the base region faces the pillar-shaped spacer and the base region has a height higher than the contact point region,
- wherein a first space is located between the opposed electrode and each of the pixel electrodes and a second space shorter than the first space is located between a front end of the contact point protrusion of the second substrate and the contact point region of the first substrate, by bringing a front end of the pillar-shaped spacer of the second substrate into contact with a front end of the base region of the first substrate.
