A display device includes: a first substrate including: a display area including a plurality of pixels, and a peripheral area positioned around the display area; a thin film transistor positioned on the first substrate; a pixel electrode layer positioned on the thin film transistor and including more than one pixel electrodes positioned in the display area; and a pixel definition layer positioned on the pixel electrode layer and including a peripheral portion overlapping a voltage transmission electrode. The peripheral portion includes a spacer and an inclination portion connected to the spacer and positioned at a first side of the spacer, and the inclination portion has a concave inclination surface.

Display device and manufacturing method thereof

Embodiments of the present invention are directed to negative active materials for lithium rechargeable batteries and to lithium rechargeable batteries including the negative active materials. The negative active material includes a crystalline carbon material having pores, and amorphous conductive nanoparticles in the pores, on the surface of the crystalline carbon, or both in the pores and on the surface of the crystalline carbon. The conductive nanoparticles have a FWHM of about 0.35 degrees (&#xb0;) or greater at the crystal plane that produces the highest peak as measured by X-ray diffraction.
