Reflective type display device
View Patent ↗According to one embodiment, a reflective type liquid crystal display device provided can suppress light leakage into a thin film transistor due to entry of extraneous light. An array substrate includes a glass substrate, a plurality of thin film transistors, a plurality of pixel electrodes, and a metal film. The plurality of thin film transistors are provided to the glass substrate. The plurality of pixel electrodes are spaced apart from each other and driven by the thin film transistors. The plurality of pixel electrodes reflect extraneous light entering the reflective type display device from a counter substrate side. The metal film is provided between a gap between the pixel electrodes and each of the thin film transistors.
1. A reflective type display device comprising:
a display side substrate;
a non-display side substrate disposed at a position facing the display side substrate; and
a light modulating layer that modulates light, the light modulating layer being interposed between the display side substrate and the non-display side substrate, wherein
the non-display side substrate comprises:
a non-display side substrate body;
a plurality of thin film transistors provided to the non-display side substrate body;
a plurality of pixel electrodes spaced apart from each other and driven by the thin film transistors, the plurality of pixel electrodes reflecting light entering the reflective type display device from a display side substrate side;
an extraneous light entry suppressing layer provided between a gap between the plurality of pixel electrodes and each of the thin film transistors, the extraneous light entry suppressing layer being a light shielding layer; and
a retardation layer that covers the light shielding layer between the pixel electrodes, and
the light shielding layer is a metal film facing a back surface side of the pixel electrodes while an insulation film is interposed between the pixel electrodes and the metal film.
2. The reflective type display device according to claim 1 , wherein the retardation layer is a λ/4 retardation layer.
3. The reflective type display device according to claim 1 , wherein the light modulating layer is a liquid crystal layer.
