var manager = configureBreezeManager();

        function configureBreezeManager() {

        breeze.NamingConvention.camelCase.setAsDefault();
        var mgr = new breeze.EntityManager('api/breeze');
        model.configureMetadataStore(mgr.metadataStore);
        mgr.fetchMetadata(function (metadata) {
            return initializeMetadataStore(mgr.metadataStore, metadata);
        });
        return mgr;
    };




       function initializeMetadataStore(metadataStore, metadata) {
        breeze.NamingConvention.defaultInstance = breeze.NamingConvention.none;
        var metadataType, metadataProperty, entityProperty, i, j;
        for (i = 0; i < metadata.schema.entityType.length; i++) {
            metadataType = metadata.schema.entityType[i];
            var entityType = metadataStore.getEntityType(metadataType.name);
            for (j = 0; j < metadataType.property.length; j++) {
                metadataProperty = metadataType.property[j];

                    entityProperty = entityType.getProperty(metadataProperty.name);

                if (entityProperty) {
                    if (typeof metadataProperty.displayName !== 'undefined') {
                        entityProperty.displayName = metadataProperty.displayName;
                    }
                    if (typeof metadataProperty.displayOrder !== 'undefined') {
                        entityProperty.displayOrder = metadataProperty.displayOrder;
                    }
                    if (typeof metadataProperty.autoGenerateField !== 'undefined') {
                        entityProperty.autoGenerateField = metadataProperty.autoGenerateField;
                    }
                    if (typeof metadataProperty.allowEmptyStrings !== 'undefined') {
                        entityProperty.allowEmptyStrings = metadataProperty.allowEmptyStrings;
                    }
                }
            }
        }

    }





        var readData = function (entityName, observableResults, showLog) {

        if (!entityName || !observableResults)
            return null;

        var query = new breeze.EntityQuery()
            .from(entityName);


        return manager.executeQuery(query)
         .then(querySucceeded)
         .fail(queryFailed);
    }

    function readEmployee() {
    return breezeDataService.readData("Employees", employees, true).then(function () {

        var propertyDisplayName = employees()[0].entityType.getProperty('lastName').displayName;//error displayName undefined
     }
    }

when I get list of entity by readData function that list (observableResults[0]) have not any displayName but I add displayName and checked it by initializeMetadataStore function is correct

FINALLY!!!!! I found it it because of breeze.NamingConvention.camelCase.setAsDefault();
