Abstract
A display device according to an aspect of the present disclosure may include a first substrate including a display area and a non-display area, a second substrate attached to the first substrate in a state in which a first sealant is disposed, a first liquid crystal layer disposed inside the first sealant, a second sealant disposed outside the first sealant, a second liquid crystal layer disposed between the first sealant and the second sealant, a first electrode disposed on the first substrate in the non-display area, and a second electrode disposed on the second substrate in the non-display area and configured to define a capacitance together with the first electrode, thereby measuring and monitoring a cell gap in a bezel area.
Claims26
A display panel, comprising:
- a first substrate including a display area and a non-display area;
- a first liquid crystal layer disposed on the display area and the non-display area of the first substrate;
- a first sealant bordering the first liquid crystal layer;
- a second liquid crystal layer bordering the first sealant;
- a second sealant bordering the second liquid crystal layer;
- and
- a capacitor formed based on a first electrode and a second electrode at opposite ends of the second liquid crystal layer for detecting stress applied to the display panel,
- wherein the first sealant is disposed on the first electrode in contact with the first electrode.
A method of manufacturing a display panel, comprising:
- forming a device layer including a plurality of thin film transistors (TFTs) on a first substrate;
- forming an insulation layer over the device layer;
- forming first holes in the insulation layer in a non-active area along a periphery of an active area of the display panel;
- forming second holes in the insulation layer that are outside of the first holes;
- forming a first conductive layer over the first holes and the second holes;
- forming a first sealant over the first holes;
- forming a first liquid crystal layer within the active area and the non-active area within the first holes;
- forming a second sealant over the second holes;
- and
- forming a second liquid crystal layer between the second sealant and the first sealant;
- and
- forming a second conductive layer over the first sealant and the second sealant, wherein the first conductive layer and the second conductive layer form a capacitor.
A display device comprising:
- a first substrate including a display area and a non-display area;
- a second substrate attached to the first substrate including a first sealant;
- a first liquid crystal layer disposed inside a region formed by the first sealant;
- a second sealant disposed outside a region formed by the first sealant;
- a second liquid crystal layer disposed between the first sealant and the second sealant;
- a first electrode disposed on the first substrate in the non-display area;
- and
- a second electrode disposed on the second substrate in the non-display area and forming a capacitance with the first electrode,
- wherein the first sealant is disposed on the first electrode in contact with the first electrode, and
- wherein the second sealant is disposed on the second electrode in contact with the second electrode.
