Abstract
The present invention provides a gas discharge panel on which color images are accurately displayed and which is easy to manufacture. The first and the second substrates face each other across an interval, forming a discharge space in between, which is filled with a discharge gas. Pairs of electrodes for sustaining discharge are provided on at least one of the two substrates, and phosphor layers are formed on the first substrate, arranged along the electrode pairs to form a matrix of discharge cells. An image is displayed by selectively illuminating discharge cells. Gap members having a given shape are provided between the first and second substrates at locations corresponding to the boundaries between discharge cells.

A gas discharge panel, which comprises (a) a first substrate and a second substrate facing each other across an interval, the interval forming a discharge space and being filled with discharge gas, (b) pairs of electrodes for sustaining discharge provided on at least one of the substrates, (c) a plurality of discharge cells formed in a pattern along the electrode pairs, and (d) a plurality of phosphor layers formed by baking a phosphor film and provided on the first substrate facing the discharge cells, each phosphor layer corresponding to an illumination color of the discharge cell, and the gas discharge panel displaying a color image by selectively illuminating the discharge cells, wherein
- a plurality of gap members having a spherical shape are disposed at locations corresponding to boundary areas between and excluding the center areas of the discharge cells, so as to separate the first substrate and second substrate, and determine the interval between the first substrate and second substrate.
A method for production of a gas discharge panel, the panel having discharge cells of each color arranged in a matrix pattern formed between a first substrate and a second substrate, the production method comprising:
- a phosphor layer forming process, for providing a phosphor layer corresponding to an illumination color of each discharge cell on the first substrate,
- a gap member distribution process, for disposing gap members having a spherical shap e at locations on the first substrate or the second substrate corresponding to boundaries between discharge cells, and
- a stacking process, for joining the first substrate and the second substrate after gap members have been applied to one of the substrates.
A method for production of a gas discharge panel, comprising:
- an electrode forming process, for forming electrodes on a first substrate,
- a dielectric element material application process, for applying a dielectric element material to cover the electrodes, the dielectric element material containing gap members situated in contact with the first substrate and the second substrate, thereby determining an interval between the first substrate and the second substrate,
- a dielectric element baking process, for baking the applied dielectric element, and
- after, the dielectric element material application process, a stacking process, for joining the first substrate to a second substrate.
