Abstract
A display device having a rear surface includes: a first polarizer having a first main surface; a second polarizer disposed closer to the rear surface than the first polarizer, the second polarizer to be opposed to the first main surface of the first polarizer; a liquid crystal cell between the first polarizer and the second polarizer; and a touch function layer between the first polarizer and the liquid crystal cell, the touch function layer having an electrode that detects a touch input, the touch function layer being disposed on the first main surface of the first polarizer.
Claims5
A display device having a rear surface, comprising:
- a first polarizer having a first main surface;
- a second polarizer disposed closer to the rear surface than the first polarizer, the second polarizer to be opposed to the first main surface of the first polarizer;
- a liquid crystal cell between the first polarizer and the second polarizer;
- and
- a touch function layer between the first polarizer and the liquid crystal cell,
- the touch function layer having an electrode that detects a touch input,
- the touch function layer being disposed on the first main surface of the first polarizer, wherein
- the electrode includes:
- a first insulating layer with an upper surface that includes first recessed portions;
- first electrodes embedded in the first recessed portions;
- a first protective layer of ink disposed on an upper surface of the first electrodes;
- and
- a second insulating layer disposed on the upper surface of the first insulating layer, where the second insulating layer separates the first electrodes from second electrodes in a thickness direction of the display device.
A method for manufacturing a display device having a rear surface and including:
- a first polarizer having a first main surface;
- a second polarizer disposed closer to the rear surface than the first polarizer, the second polarizer to be opposed to the first main surface of the first polarizer;
- a liquid crystal cell between the first polarizer and the second polarizer;
- and a touch function layer between the first polarizer and the liquid crystal cell, the touch function layer having an electrode that detects a touch input, the method including:
- rotating a recess forming tool about a central axis to press a plurality of protruding portions on a surface of the recess forming tool into an upper surface of a first insulating layer to form first recessed portions in the upper surface of the first insulating layer;
- partially filling the first recessed portions with an electrically conductive material to form first electrodes of the electrode;
- applying a first protective layer of ink on an upper surface of the first electrodes;
- applying a second insulating layer to the upper surface of the first insulating layer;
- and
- forming second electrodes in the second insulating layer such that the second insulating layer separates the first electrodes from second electrodes in a thickness direction of the display device.
