Function glass display units didn’t disturb a way to display only the interesting and comprehensive a way to what viewer wants  to know about the form of components and information on the monument, installations heritage, and with the progress of humanity the requirements, functions of display units has increased  not only to achieve the needs of the monument effective display and protect it from environmental changes and human intervention but also increased those requirements units to be creative in itself to stimulates monument value and reflects what is inside of the magic value, and with the multiplicity of those jobs was a Design effective glass display units is best suited to achieve the requirements of monument and Monumental and Heritage  buildings with different quality of those requirements. Problem of the research: • Not to take advantage of the possibilities of modern technology and developments in the design effective glass display units to increase efficiency of the functionality, to confirm the artistic value of monument and Monumental and Heritage  buildings. • The need of specific  and study the Considerations of Design effective glass display units and its relation  with achieve the jobs and  requirements for conservation, Display  monument in the Islamic Monumental and Heritage  buildings. Importance of the Research: • Research contribute in raising the effectiveness of performance  for conservation, Display  monument in the installations Islamic Heritage  , thus contributing to confirm the creative interaction and Cultural communication  for heritage and tourism building . Objective of the Research: • To reach a scientific and technical bases to develop a Considerations of Design effective glass display units, to raise the efficiency of its functionality for conservation, Display and confirm the artistic value of the monument of Monuments and Heritage buildings. Hypotheses of the Research: • The scholar supposes that by the characterization and classification  of  glass display units and tracing requirements could be reached to determine the Considerations of  Design effective glass display units To increase efficiency of the functionality and that detects the quality and the properties of glass and methods of design for display units that can achieves  those functions effectively display, conserve, and protect. Results: A search has been reached to the following results: determine the Considerations of  Design effective glass display units depending on the requirements of the following functions: - considerations are Achieve functions and display requirements - considerations are Achieve and functions and the requirements of conservation - considerations are Achieve jobs and protection requirements - it was revealed about the quality of some of the characteristics and properties of glass Which used to Achieve those functions depending on the type of glass display units requirement in an attempt To increase efficiency of the functionality and  confirm the artistic value for Display, conservation methods
