    Abstract: PROBLEM TO BE SOLVED: To improve the mechanical strength and to satisfactorily emit electrons, even at a high electric field by constituting the protruding part of a cathode electrode so as to have an inclined surface which is thinned toward the tip. SOLUTION: In a cathode electrode layer 10, an inclined surface 14 is formed on a protruding part 13 in order to reduce the radius of curvature of an opening end 10B. Therefore, since only the opening end 10B is made fine in the cathode electrode layer 10, and the other part is formed into a prescribed thickness, the cathode electrode layer 10 mechanically has high strength. As a result, although a dynamic force acts on the protruding part 13 of the cathode electrode layer 10, when the electric field generated from a first gate electrode layer 8 and a second gate electrode layer 12, the cathode electrode layer 10 will not break with respect to the force generated thus. Accordingly, this electron- emitting device can be operated even at a voltage which generates a large electric field.

    Abstract: PURPOSE: To decrease the dependency on the visual angle while maintaining resolution, luminance and contrast by forming a diffusing layer consisting of transparent beads and a light-absorbing member on the front side of a liquid crystal panel. CONSTITUTION: Two polarizing films 4a, 4b which hold a liquid crystal panel 3 are arranged in such a manner that the polarizing axis of the first polarizing film 4a in the front side of the liquid crystal panel 3 and the polarizing axis of the second polarizing film 4b in the back side of the panel 3 are perpendicular to each other. A diffusing layer 7 is formed in the front side over the first polarizing film 4a and has such a structure that transparent beads 11 are densely deposited to form one layer and the space in the front face of the bead layer is filled with a light-absorbing material 12. By forming the diffusing layer 7 comprising transparent beads 11 and light-absorbing material 12 in the front side of the liquid crystal panel 3, the light emitted from the liquid crystal panel 3 is diffused by the transparent beads 11 so that a good image for a wide visual angle can be given to the observer.

    Abstract: PROBLEM TO BE SOLVED: To provide an organic EL display device which reduces unevenness in the luminance of emitted light due to an increased size or heightened definition, thereby improving display quality.SOLUTION: The organic EL display device comprises an element substrate having an organic layer including a first electrode and an organic electroluminescent layer and a second electrode in that order on a first substrate and a counter substrate disposed oppositely to the element substrate via a sealing layer. The counter substrate includes a laminate layer composed of an inorganic light-shielding layer and a conductive layer which are each laminated on a second substrate, the conductive layer having lower resistance than the second electrode and being electrically connected to the second electrode on the element substrate. The inorganic light-shielding layer and the conductive layer can be formed into patterns with high accuracy, so that, even when the second electrode on the element substrate has high resistance, voltage drop arising therefrom is restricted.
